Appliance Repair Questions? Ask a Technician for Answers ASAP
What appliance is this and what is the model number?
Since your repair person isn't coming til Friday, give this a try, open the door and unplug from wall for 5 minutes then close the door and plug it back in. See if that does anything for you, thank-you. Still get back with me either way.
Okay, Good luck with your technician.
