Common symptoms
Microwave runs but does not heat
The turntable or light may work while food stays cold, which can point to a magnetron, diode, capacitor, or related high-voltage issue.
Door will not latch or start properly
A worn latch, misaligned door, or failing door switch can stop the microwave from starting or cause it to shut off unexpectedly.
Sparking or arcing inside the cavity
Metal objects, damaged waveguide covers, food debris, or interior damage can lead to visible sparks and should be checked right away.
Microwave has no power
If the display is blank or the unit will not respond, the issue may involve the outlet, fuse, control board, or internal wiring.
Buttons or display are unresponsive
A faulty control panel, membrane keypad, or electronic board can keep the microwave from accepting commands.
Repair process
1. Initial symptom check
We start by confirming what the microwave is doing, including whether it powers on, heats, sparks, or fails at the door.
2. Safety and access inspection
We inspect the door latch, switches, cabinet fit, and visible components before moving to electrical testing.
3. Electrical and control diagnostics
Testing helps narrow down issues with fuses, wiring, control boards, interlocks, and high-voltage components.
4. Repair recommendation
After identifying the likely cause, we explain the repair path and discuss the most practical next step for your unit.
5. Functional verification
Once repaired, the microwave is tested to confirm safe operation, proper door response, and consistent heating.
Common Microwave Problems We See
Microwave issues often show up as no heat, intermittent heating, a door that will not secure properly, sparking inside the cavity, or a unit that appears dead. In many cases, the problem is tied to the door-interlock system, high-voltage parts, or the control electronics. Identifying the exact failure point matters because similar symptoms can come from different causes.
What We Check During Diagnosis
A microwave repair visit typically includes checking the outlet and power path, inspecting the door latch and interlock switches, reviewing the control panel response, and looking for visible burn marks, broken components, or signs of arcing. This approach helps separate simple issues from more serious electrical faults.

Maintenance tips
Frequently Asked Questions
Why does my microwave run but not heat?
This usually points to a problem in the heating circuit, such as the magnetron, diode, capacitor, or another high-voltage component. A proper diagnosis is needed because several parts can create the same symptom.
Is a sparking microwave dangerous?
Yes. Sparking or arcing can indicate damaged interior surfaces, debris, or component failure. It is best to stop using the microwave until it is inspected.
Can a bad door switch stop the microwave from starting?
Yes. Door-interlock switches are designed to prevent operation when the door is not fully secured. If one fails, the microwave may not start or may shut off unexpectedly.
Do you repair all microwave types?
We service many common residential microwave styles, including countertop, built-in, and over-the-range units. The repair path depends on the model and the specific problem.
Should I keep using a microwave with intermittent power?
It is not a good idea. Intermittent power can signal an electrical or control issue that may worsen over time and should be checked promptly.
