Problem With Elec. Ceiling Heat
Hi guys,

I am new to the site. I have a ceiling electric heat unit that will turn on but will not turn off when the t-stat tells it to. it was installed new about four years ago and has not acted up any untill recently. At first I thought it was the t-stat and replaced it with a new one. Still will not turn off. I can here the t-stat click when the desired temp is reached but the heater keeps blowing hot air. However, If I turn the t-stat to the off position, it will then cycle off. It sounds to me like there is a relay or limit switch hanging close and allowing the heat element and blower motor to stay on when the t-stat sends a signal to turn off. How can I test the unit and how difficult is it to replace the relay or limit switch?

Thanks for any help, Mike

without seeing the unit we can only speculate on the difficulty of repair.
I think you have correctly diagnosed the problem.
