Customer Question
Hi, My old 30yrs plus thermostat...
Hi,
My old 30yrs plus thermostat is acting funny. Celsius on left, Fahrenheit on right, and unless it is set to on position it won't start running at all. Then in the on position of course it never shuts off. When the unit is in off positon it will make a clicking noise once in a while.
Thanks,
Helene

***I am out of work 1-1/2 yrs and would rather not have to buy anything.

***The unit is turned off but it just clicked like it is try to turn on!!!
