It's fall, I'm trying to get a bunch of things done before winter sets
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.
