my fairly new hiel furnace does not want to stay on. i thought it was
the thermostat so i removed it and twisted the red and white wires
together. the exaust fan kicks on and after about 45 seconds the main
blower fan kicks in and then shuts off. the burners flame up for a
second or two. the exaust fan stays on the whole time. any tips/ideas?
it's colder than *uck here in michigan!!
Sounds like the flame sensor is not working. it is a small metal rod
on one wire that sits in front of one of the burners (some are
straight, some are angled at 90 or 45 degrees). Unplug the furnace,
take this rod out and clean it with a file. If that doesn't work then
replace the sensore.
Heils got a 5 year parts warranty on it.
Call a Heil or other licened dealer and have them come out and repair the
issue. sounds like either a bad flame sensor, or..and dont laugh...reversed
polarity at the unit.
Have you had any electrical work done lately?
