At installation, one of 2 lights in the microwave was found to be inoperable. We elected to ignore this issue until the 2nd light burns out because the oven would have to be removed to replace the bulb and to verify that the bulb circuit is functional. Now the unit has started malfunctioning due to “error detected” with instructions to turn off the breakers for 30 sec- this results in brief periods of function, but the process continues to occur. I’ll be calling the service number again. Not pleased!
