That is 38th of the 50 states with any, against 14 in Texas. Microwave work is a narrower speciality than the everyday kitchen and laundry calls, so coverage is thin in most states. 7 other appliance businesses are listed in Delaware, and general technicians will often take this work once they know the model. Have the model number ready when you call.
Counted from the 2 profiles above, not from a survey. Everything a business states about itself is reported as a claim.
Delaware holds 2 listed microwave repair businesses, out of 209 nationwide. That ranks 38th of the 50 states with any, level with Arkansas and behind Texas on 14. They are 2 of the 9 businesses listed in Delaware — 22% of the state directory.
Their ratings average 4.7, against 4.6 across all 209 listed nationwide, and 2 of the 2 sit at 4.5 or better. None holds a straight 5.0, and none sits below 4.0. Between them they carry 216 reviews, the largest single tally being 156 on ABC Sales & Service Inc in Wilmington. Rating and review volume are what the businesses' own public profiles report — treat a high average on six reviews differently from the same average on six hundred.
All 2 state that they are licensed, and all state that they carry insurance. On top of that, 1 shows a Better Business Bureau accreditation in the profiles. None advertises round-the-clock emergency cover, but 1 advertises same-day service. All of that is self-stated in the listing, not verified here: ask for the license number and a current certificate of insurance, and for anything that opens a sealed refrigerant system ask to see federal EPA Section 608 certification, which is required in all fifty states.
2 of them publish a founding year: the longest-established has been trading since 1941, and the median across those that say is 49 years. 2 of them work out of Wilmington, the only Delaware city with an index page that holds any. Between them they name 6 distinct towns, suburbs and neighborhoods in their stated service areas, so coverage reaches well past the cities listed here — give your address when you call rather than assuming.

The 5 most common microwave faults, and whether each is homeowner work or a job for a licensed technician.
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→Completely dead, no display, no fan
TechnicianA blown line fuse — and that fuse is usually blown by a failing door interlock switch, so replacing the fuse alone rarely holds.
Loud buzzing or humming while heating
TechnicianA failing magnetron or a high-voltage transformer starting to break down. Stop using it and have it tested.
Sparking or arcing inside the cavity
TechnicianA burnt or missing waveguide cover, chipped cavity paint exposing bare metal, or metal in the food. Stop immediately — arcing damages the magnetron fast.
Step-by-step: Microwave Sparking Inside→Turntable does not rotate
TechnicianThe turntable drive motor or a stripped coupler. The one genuinely low-cost microwave fault.
Step-by-step: Microwave Turntable Not Turning→10 published microwave guides. A diagnostic fee is $40–$80 before any work starts, so half an hour with a flashlight is worth spending.
Ask the technician to walk you through these while they are on site — every one of them prevents a fault in the list above.
Wipe the cavity and check the waveguide cover for burn marks
WeeklyPrevents: Arcing, which destroys magnetrons quickly and permanently.
Wash or replace the grease filters (over-the-range)
Every 3 monthsPrevents: Loss of extraction and a vent motor running against a blocked path.
Replace the charcoal filter on recirculating models
Every 6–12 monthsPrevents: Cooking odours pushed back into the room.

Every state with a listed microwave specialist, most first. Delaware sits 38th of 50 on 2.
National ranges for parts and labor together, before the $40–$80 diagnostic. Labor tracks local wages and drive time, so metro Delaware sits toward the top of each range and rural calls toward the bottom, while the part costs about the same anywhere. Nothing here is a quote.
| Repair | Parts + labor |
|---|---|
| Turntable motor or couplerThe cheapest genuine microwave repair. | $80–$160 |
| Door interlock switch setReplaced as a set; a single switch rarely fails alone. | $100–$200 |
| Line fuse plus the interlock that blew itFuse-only repairs usually fail again within weeks. | $100–$200 |
| Vent fan motor (over-the-range)Check the filters first — they mimic a dead fan. | $150–$300 |
| High-voltage diode or capacitorDischarging the capacitor safely is the whole reason this is not DIY. | $150–$280 |
| Magnetron replacementWorth it on a built-in; almost never on a countertop unit. | $150–$350 |
7–10 years. Over-the-range units land at the lower end because they run hot above a cooktop and their filters are neglected. When replacing beats repairing covers the 4 cases where the maths turns, in full.
Blue Book
A quote above $125 on a microwave past 6 years old is usually better spent on a replacement.
