Quick reference
Display: the 18 power watch code
Reported problem: the electronic control of the microwave
Reset to try: shut off the breaker or fuse feeding the microwave for 30 seconds
If it persists: GE says service may be needed
Why a power cycle is suggested
GE notes that interrupting the supply at the breaker or fuse for half a minute can sometimes make the code go away. The same article admits that some cases still call for service, so a code that survives the reset needs attention.
Messages that look alike
PF, 888 or 8888: shown after installation or a power return, and not a fault
When the 18 power watch code remains after the breaker reset, reach us at (415) 729-2045 from San Francisco or elsewhere in the Bay Area. Please have the exact code wording, the model number and the reset you carried out. Our microwave repair page describes the work.
Model compatibility: GE reuses codes across series and model years, so 18 power watch code may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.

The 18 power watch code reports a problem with the microwave electronic control.
Important safety warning. Do not attempt repairs involving electrical components, gas, water lines, refrigerant or sealed systems. Unplug the appliance if it is safe to reach the outlet, and leave internal diagnostics to a qualified technician.
