A Bosch microwave that quits halfway, won't latch its door, or flashes an E or ER code has a specific, findable cause. Some of those codes, overheating above all, call for you to stop using it right away.
In the order we see them across Houston homes.
Built-in microwaves hide in tall cabinets, often above a wall oven, where heat and steam rise all day. Door-latch sensors, a temperature probe, and the control board keep watch, and when one of them objects you get an E or ER code and a cold plate of leftovers.
We sort those codes by urgency. E3 (the door system) and ER1 (temperature sensor) can usually wait for a normal appointment, while ER4 means stop now. Then we test the latch switches, probe, board, and heating parts one at a time. Because the microwave is tucked into cabinetry, we plan the work so that nothing around it gets scratched. You get a written price before we start, and a clear answer on whether repair makes sense.
Trained on Bosch microwave controls and diagnostics.
Genuine OEM parts, stocked for the most common repairs.
A written price, approved by you before any work starts.
A 30-day workmanship warranty on every repair.
Yes. ER4 signals extreme overheating, which carries a fire risk. Unplug the microwave or switch off its circuit, leave it off, and book a diagnostic before it is used again.
Often not. Some control-board and door-latch jobs do require pulling it partway, and our technicians do that carefully so the cabinetry and trim kit stay unmarked.
Arcing may come from metal touching something, a damaged waveguide cover, or a magnetron problem. Stop using the oven at once, because each cause needs a professional look.
