I have an old gravity furnace and recently it's been cold enough to
where it should have come on. But, even when I set the temp to 90, it
still won't turn on. I've replaced the thermostat because I was told
that these types of furnaces basically contain no moving parts to
break, so I figured it might be the thermostat. Well, still no dice.
What else can I check/do to get it to turn on? It worked fine last
winter and we didn't do anything to it but turn down teh thermostat
when it started getting warmer. Thanks!
At the base of the furnace is the unit that turns it on/off. I took
the cover off of it and wiggled some of the wires and it turned on. I
then went and turned the thermostat down and it shut off. Then I
turned the thermostat back up, but it didn't come on again. I tried
wiggling the wires again, but no luck. Anyone have any ideas? Thanks.
