It's fall, I'm trying to get a bunch of things done before winter sets in.
My OLD Lennox Electric Forced air whole house heater (was installed in
1970) has the original Lennox Thermostat.It's the round dial-type with a slider on top of the dial that you set to desired temperature. Mercury bulb inside. It worked well until the end of last winter, when I noticed that if I set it at 68 degrees, it might go to 72 degrees or so until it shut down the heater.
Wifey has turned the heater back on and I am back with the beast not shutting down at 68 degrees (Oh, it will occassionally, I think).
Anyway, is there a way to fix this....or do I just need to buy a new thermostat. If I buy a new one, any suggestions? I do not want one of the programmable "bells and whistles," model.
Just another basic would be fine. Meanwhile, wife is very happy with the heater shutting off in the mid-70s range...me, not so much.
