Has anyone had a problem with their Dometic microwave? I just replaced one that is less than 2 years old and the new one I put in seems to have a glitch in the electronics. Every once in a while when it is running it will shut off and the read out will say "Please set time of day". When you reset the time it will run fine until it does it again. Usually days before it does it again. Has anyone had a similar problem?
