Troubleshooting and error codes
| Problem | Possible Cause & Solution |
|---|---|
| Microwave oven does not start |
Power cord is unplugged, door is open, or cooking time has not been set. • Plug in power cord. Or, check for a blown circuit fuse or a tripped main circuit breaker. • Close oven door. • Set cooking time. Timer function started. If the display shows a time counting down but the oven is not cooking, check to see if a Timer function has been started instead of a cooking function. A fuse in your home may be blown or the circuit breaker tripped. Or the appliance is connected to a GFCI (Ground Fault Circuit Interrupter) outlet, and the outlet's circuit breaker has tripped. • Check the main electrical box and replace the fuse or reset the circuit breaker. Do not increase fuse capacity. If the problem is a circuit overload, have it corrected by a qualified electrician. Reset the circuit breaker on the GFCI. If the problem persists, contact an electrician. |
