Appliances serviced, and what those repairs cost
Certainty Appliance Repair LLC lists 8 of the twelve appliance types in this directory. Each row links to the full repair reference for that appliance and carries four national figures: the diagnostic visit, the typical all-in repair, what a comparable new unit costs, and how long the appliance is expected to last.
| Appliance | Diagnostic | Typical repair | New unit | Avg. life |
|---|---|---|---|---|
| Refrigerator repair | $50–$120 | $200–$400 | $1,200 | 14 yrs |
| Freezer repair | $50–$120 | $150–$400 | $600 | 15 yrs |
| Ice Maker repair | $50–$100 | $150–$400 | $400 | 8 yrs |
| Oven & Range repair | $50–$120 | $100–$500 | $1,000 | 14 yrs |
| Dishwasher repair | $50–$100 | $150–$300 | $700 | 10 yrs |
| Dryer repair | $50–$100 | $100–$350 | $750 | 12 yrs |
| Microwave repair | $40–$80 | $50–$200 | $250 | 9 yrs |
| Washer repair | $50–$100 | $150–$350 | $800 | 11 yrs |
These are national bands, not quotes for Denver, CO. Labor rates track local wages, insurance, and drive time, so the same job costs measurably more in a dense, high-cost metro than in a smaller market, while the part itself costs roughly the same anywhere. Sealed-system refrigerant work, built-in installations, and luxury brands sit at the top of every range because fewer technicians are certified for them and parts are ordered rather than stocked. Get two or three quotes before you commit.
A quote is worth checking against the appliance's remaining value. The rule of thumb built into our value estimator: replace rather than repair once the quote passes about half the price of a comparable new unit and the appliance is past roughly two-thirds of its expected service life. Under both thresholds, repair is almost always the cheaper decision.
Brands serviced, and what each tier means
Certainty Appliance Repair LLC names 10 brands. Price tier decides more about a repair than the badge does: it sets what a part costs, where it comes from, and whether a general technician can buy it at all.
Components are inexpensive and stocked by every general parts retailer, so a pump, a lid switch or a thermal fuse is a same-week fix. The trap is labour: a $250 repair bill against a $450 machine is rarely worth authorising, so ask for the parts figure and the labour figure separately.
Any qualified appliance technician can work on these. There is no authorised-only network to hunt down, so choose on rating, licensing and how clearly the technician explains the fault.
The best-stocked parts situation in the trade. OEM components are easy to source, aftermarket equivalents exist for most of them, and a technician will often have the common failure on the van rather than ordering it.
Any qualified technician can take the job. Factory-authorised service mainly matters while the machine is still in its warranty period — outside it, an experienced independent is usually faster and cheaper.
OEM parts cost noticeably more and the aftermarket is thinner, so expect an order-and-return visit on anything past the common failures. Because the machine is worth more, a part that would total a budget unit is often still the right call here.
Most independent technicians work on this tier, but ask whether they have had factory training on the line. Control boards, inverter drives and door mechanisms diverge enough between premium platforms that experience is not interchangeable.
Common faults on the appliances they service
Symptom, the cause it most often turns out to be, and whether it is homeowner work or a job that has to go to a technician. Knowing which one you probably have before you call shortens the visit — and sometimes removes the need for one.
- Technician
- Needs a technician — meter diagnosis, a model-matched part, or teardown that is easy to get wrong.
- Homeowner fix
- Safe for a homeowner with basic tools once the appliance is unplugged or the breaker is off.
- Refrigerator
Fridge side is warm but the freezer is still cold
TechnicianThe evaporator fan has stopped, or the damper between the two compartments is stuck shut. One evaporator cools both sides on most modern units, so the freezer holds temperature longest.
Step-by-step: Refrigerator Not Cooling - Freezer
Not holding temperature but still running
Homeowner fixCondenser coils packed with dust, a failed door gasket, or a thermostat that has drifted out of calibration.
Step-by-step: Freezer Not Freezing - Ice Maker
No ice at all, mould is dry
TechnicianNo water arriving: a closed shut-off, a kinked supply line, a frozen fill tube, or a failed water inlet valve.
Step-by-step: Ice Maker Not Making Ice - Oven & Range
Oven will not reach temperature or will not heat at all
TechnicianA failed bake element on an electric oven, or a weak igniter that no longer draws enough current to open the gas safety valve.
Step-by-step: Oven Not Heating At All - Dishwasher
Dishes come out with food residue still on them
Homeowner fixBlocked spray-arm jets, a filter that has never been cleaned, or inlet water below 120°F. Rarely the wash pump.
Step-by-step: Dishwasher Not Cleaning - Dryer
Tumbles but produces no heat at all
TechnicianA blown thermal fuse — usually triggered by a restricted vent — or a failed heating element on an electric machine, or an igniter on a gas one.
Step-by-step: Dryer Not Heating - Microwave
Runs, lights up, turntable spins, but food stays cold
TechnicianThe magnetron, high-voltage diode, or capacitor has failed. The control side works because it is on a separate low-voltage circuit.
Step-by-step: Microwave Runs But Doesn't Heat - Washer
Fills and washes but will not drain
Homeowner fixA blocked pump filter, a kinked drain hose, or a seized drain pump. On front-loaders the filter behind the lower access panel is the first place to look and is free to clear.
Step-by-step: Washer Won't Drain - Refrigerator
Nothing is cold and the compressor clicks every few minutes
TechnicianA failed start relay or overload protector. The relay plugs into the side of the compressor and rattles when it has failed — the classic five-second test.
Step-by-step: Refrigerator Not Cooling - Freezer
Heavy frost build-up on the walls
TechnicianOn a frost-free model, a failed defrost heater or thermostat. On a manual-defrost chest freezer, a door seal letting humid air in.

Refrigerator
Refrigerator Not Cooling — Narrow It Down Before You Buy Parts
A refrigerator that has stopped cooling is not one fault but a family of them, and the fastest way to narrow it is to look at the freezer before the fridge. If both compartments are warm, the problem is in the machinery that makes cold — power, the condenser, the compressor circuit. If the freezer is still making ice but the fresh food section has gone warm, the cold is being made and not delivered, which points at airflow rather than refrigeration. Everything below is ordered so the free checks come first and the expensive conclusions last.

Freezer
Freezer Frost Buildup — Diagnose the Defrost System
Where the frost is tells you what is wrong. A thin, even dusting on the evaporator coil is normal — every frost-free freezer builds a little and melts it off several times a day. A thick slab of ice packed into the coil fins means the defrost system has stopped working. Frost concentrated around the door or on the food itself means humid room air is getting in. And a manual-defrost chest freezer with even frost on the walls is simply due for its annual defrost and has nothing wrong with it at all.

Ice Maker
Ice Maker Not Making Ice — Full Diagnostic Sequence
An ice maker that has stopped completely is a sequence problem: the machine needs a signal to start, water at adequate pressure, a clear path for that water, and a cold enough freezer to trigger the harvest. Break any link and you get zero ice with no error message. Work the chain in order, and give the machine a full 24 hours after each change before you judge whether it worked — a healthy household ice maker only produces a batch every 90 minutes or so.

Oven & Range
Oven Not Heating Evenly — Map the Problem Before You Fix It
Uneven baking and a miscalibrated oven are two different faults that get reported with the same words, so the first job is to tell them apart. An oven that is simply running cool or hot everywhere at once needs calibrating and nothing else. An oven that browns one corner of a tray and leaves the opposite corner pale has an airflow, element or door problem, and no amount of offset adjustment will help. Twenty minutes with a slice of bread will tell you which one you have, and that determines everything that follows.

Dishwasher
Dishwasher Not Cleaning — Find Out What It Is Short Of
A dishwasher cleans with four things: hot water, enough of it, spray pressure, and detergent that gets released at the right moment. When dishes come out gritty, one of those four is missing, and the job is to work out which. Be precise about the symptom first, because it points at different faults — food particles left stuck on is a spray or filter problem, a chalky white haze is a water hardness and rinse aid problem, and food redeposited as a fine grey film across everything is a filter or drain problem. This guide covers the first of those.

Dryer
Dryer Not Heating — Electric and Gas, Diagnosed in Order
A dryer that tumbles happily but leaves clothes cold and wet has lost its heat source, and the diagnosis splits immediately on fuel type. On an electric dryer, the two things worth checking before you open the cabinet are the cycle setting and whether the machine is still receiving both of its 240-volt legs — between them they account for a great many no-heat calls and neither costs anything. On a gas dryer, the ignition sequence is visible through the burner opening, and watching one cycle tells you which of three parts has failed. Work through the shared checks first, then take the branch that matches your machine.

What the parts cost
The components that most often fail on these appliances, with typical retail prices for the part alone. Labor is not included, and these are not this company's prices — they are what a homeowner pays a parts retailer, so you can see how much of a quote is part and how much is labor.
| Part | Appliance | Typical price | Fitting |
|---|---|---|---|
| Water Filter | Refrigerator | $25–$60 | Easy |
| Start Relay and Overload | Freezer | $12–$45 | Easy |
| Water Filter | Ice Maker | $25–$70 | Easy |
| Bake Element | Oven & Range | $15–$40 | Easy |
| Spray Arm | Dishwasher | $15–$40 | Easy |
| Thermal Fuse | Dryer | $5–$20 | Easy |
| Turntable Motor | Microwave | $15–$30 | Easy |
| Drain Pump | Washer | $30–$80 | Moderate |
| Door Gasket | Refrigerator | $30–$80 | Easy |
| Door Gasket | Freezer | $40–$140 | Easy |
| Water Inlet Valve | Ice Maker | $30–$100 | Moderate |
| Oven Temperature Sensor | Oven & Range | $15–$30 | Easy |
A part that costs $30 inside a $250 quote is normal — the rest is the trip, the diagnosis, and the labor. A part that costs $300 is the point at which the repair-or-replace question is worth asking properly. Ask for the part figure and the labor figure separately on any written estimate.

Questions to ask Certainty Appliance Repair LLC before you book
The record lists Certainty Appliance Repair LLC as licensed and insured, and names 1 certification. That is what the source published, not something we verified — so the checks below still apply.
Ask for the license number, then verify it yourself
There is no single national appliance repair license. Requirements are set state by state, and in some places by the city or county, so the only reliable check is the paperwork. Ask which license or registration the company works under, get the number, and confirm it is active with the authority that issued it before you book.
Get proof of liability insurance, not a verbal assurance
A technician works on your water lines, your gas line, and your electrical circuits. Ask for a current certificate of general liability insurance in the company's name and check that the policy is in force on the day of the visit. A company that carries it will send the certificate without hesitating.
Require EPA certification for any sealed-system work
Section 608 of the federal Clean Air Act requires EPA certification for anyone who opens a sealed refrigerant system. That covers refrigerators, freezers, ice makers, and wine coolers. If a quote involves recovering, recharging, or brazing refrigerant lines, ask to see the certification before the work starts.
Separate the diagnostic fee from the estimate
Most shops charge a service-call or diagnostic fee to send a technician out, and many credit it toward the repair if you go ahead. Ask what the fee is and whether it is credited, then ask for a written estimate that itemizes parts, labor, and any trip charge before you authorize the job.
Put the warranty term on the estimate
Parts and labor are usually guaranteed for different lengths of time and the terms vary by company, so ask for both in writing rather than assuming. Ask specifically who pays for the return visit if the same fault comes back within the term.
Pay on completion, and keep the itemized invoice
A deposit against a special-order part is normal; a large up-front payment for the whole job is not. Pay the balance once the appliance has been tested in front of you, and keep the itemized invoice — you will need the part number and the labor term for any warranty claim later.
Have this ready when you call
For refrigerator work specifically, these are the answers that decide which parts get loaded on the van — and whether the first visit is the only visit.
- Model and serial number — the tag is inside the fresh-food compartment, usually on the left wall or behind a crisper.
- Whether the freezer still freezes. This one answer separates an airflow fault from a sealed-system fault.
- Any error code shown on the dispenser or control panel.
- How long it has been happening, and whether it started after a power cut.
- Whether you can hear the compressor hum with the door closed.
How Certainty Appliance Repair LLC compares in Denver
