What to expect when you call Pinnacle Appliance Services for this service
A microwave that hums but does not heat, sparks inside the cavity, or has a door latch that will not engage is dealing with one of several well understood failure points. Our Roberts, WI technicians work on countertop, over the range, and built in microwave models, testing the magnetron, high voltage diode, capacitor, and door interlock switches as part of a safe, thorough diagnostic.
Because microwaves store high voltage even after being unplugged, this is one appliance category where professional repair matters for safety as much as for convenience. Our technicians follow proper discharge procedures before opening the housing, protecting both themselves and your household from an unsafe repair attempt.
Over the range models add ventilation fan and light assembly service to the list of common repairs, since these units double as a range hood for the cooktop below. We service both the cooking function and the ventilation function together so the whole unit works as intended.
A clear, straightforward path from your first call to a working appliance

The technician completes the repair using quality matched parts, then runs a full function test to confirm the appliance is working correctly before leaving.
