My name is Garry. I'll be happy to assist you with your heater.

When you state, "nothing on the control panel will work", is the display also blank, where you are not seeing the set temp or anything else?

Customer: replied 1 year ago.
That is correct. No lights on control panel on heater. I checked the transformer. It is warm and I am getting power.
