Whirlpool Microwave Error Codes - Appliance Fault Codes

The first thing to try is switching the Microwave main power supply off for 60 seconds. This usual only works if the fault was set due to a supply voltage fluctuation from a storm or power outage. It may also work if the problem is intermittent. Unfortunately this might only be a short term solution because if the problem is intermittent and the fault returns, the error code will display again.

If that doesn’t work, the problem triggering the error code will need to be repaired in order to clear the fault code.
