I've just moved into a new home that was fitted with a (circa 1982) Gaffers & Sattler / Magic Chef forced air heating system (model # AC13-U80-5!!).
Like all new homeowners, I'm strapped for cash, which means I'd like to find the most economic solution to my problem!
Now, I've never had a forced warm air heating system before, so I'm not too sure what to expect, so please bear with me if my questions are a bit dumb! I'm trying to figure what isn't working! There is some room heating occurring, but it doesn't seem to 'right'. BTW There is no air con unit involved!!
We live in Southern California and so the situation I'm describing is late at night / in the early-mid morning when temperatures outside are lower.
1) With the thermostat set to 85degF, the room temperature (as measured by the thermostat, and another thermometer) is on 65degF and the furnace is only lit and / or blowing every few minutes. My wife and I have resorted to cuddling to keep warm. :)
I assume that the thermostat is shot - do you agree?
2) a) I hear the furnace light up, but the blower doesn't come on; b) Then one of two things seem to happen: i) The blower comes on and we get some warm air; then the furnace goes out; OR ii) The furnace goes out; then the blower comes on c) The blower continues and we get cool air; d) The blower stops.
When the cycle is (a,bi,c,d) we get some heating, but the cool air at stage c is annoying but tolerable. When the cycle is (a,bii,c,d) there seems no point to it at all other than wasting energy! It's worthy of note that very often after the blower stops at stage (d) the cycle starts again at (a).
Help! I've no idea what is going on here ... is this normal?
