I have a 1964(ish) Lennox natural gas apartment-size furnace that runs
its blower constanly without regard to whether the thermostat has
kicked on. The only thing the thermostat seems to control is the
burners. Is this normal?
If not, what should I be looking for as a possible cause and what
should I do to repair it?
Any advice would be great.
put in a new fan limit switch. good luck finding the correct oem part
however. I believe the correct terminology in this case is.......
How many cracks n holes do you suppose there are in that 40+ yr old
heat exchanger? Not worried about CO poisoning your family to death?
Well... I was trying to decide whether to press my landlord to replace
it or at least fix it, since it's consuming electricity constantly. The
other concern I have is that the exhaust is hot as blazes and the air
coming through the ductwork is only lukewarm.
I think it's a safe assumption that no aspect of this unit is effecient
in the least.
I'll have to see what the landlord says.
