It was an excellent experience. My built-in ice maker was fixed quickly and hasn’t had any issues since. The prices are affordable, and the service quality is excellent.

Microwave Runs but Does Not Heat
A running turntable and interior light do not guarantee heating output. No-heat complaints usually come from the safety-switch chain or high-voltage section.
Typical symptoms
- Timer counts down normally but food stays cold
- Loud hum or buzz during heat cycle attempts
- Intermittent heating on some cycles only
- Unit runs then shuts off early
Common causes we verify
- Door switch chain not proving closed consistently
- High-voltage diode or capacitor failure
- Magnetron output failure under load
- Control relay not supplying high-voltage circuit
- Thermal cutoff opening during heat cycle
Microwave high-voltage systems are hazardous even when unplugged. We do not recommend internal DIY repair on no-heat symptoms.
How We Diagnose Microwave No-Heat Complaints
We confirm safe door-switch logic first, then test high-voltage path behavior and control output.
Door interlock verification
Microwave heating is gated by door switch state. Worn switches can cause intermittent no-heat.
High-voltage path checks
We test diode, capacitor, and related high-voltage behavior using safe procedures.
Magnetron performance
A weak or failed magnetron can run noisy while producing little or no heating.
Control relay and thermal protection
We confirm command output and whether thermal cutoffs are interrupting operation.
Repair vs Replace for No-Heat Microwaves
Door-switch and control-side fixes are often practical. Magnetron and high-voltage assemblies vary by model and age, so we quote after confirmed tests (typical labor $109-$209, parts extra).
Microwave Not Heating FAQ
Austin no-heat questions we hear most.
Why does the microwave run if it is not heating?
Motor, fan, and display can run while the high-voltage heating path fails.
Is this safe to keep using?
No-heat with loud humming or intermittent shutoff should be diagnosed before further use.
Can I replace the high-voltage parts myself?
We do not recommend internal microwave HV repairs due to stored high-voltage hazards.
Does the $39 diagnostic apply toward repair?
Yes, it applies toward the repair total if you proceed.
