do you ever see a glow or 3 seconds of flame?..or nothing?
ok, in front of the burner is the ignitor and also a flame sensor.
We need to clean the flame sensor with steel wool...shown here
you see where the glow is?
That burner gun must come out.
It is a bit tedious on this model..but the flame sensor is where the flame comes out.
Correct....gas valve shuts off, undo gas pipe....remove screws...pull assembly straight out...
Clean the sensor and install..
Turn on gas, turn on electric, turn thermostat to heat and up.
May take 2 cycles...the flame sensor gets a clear glaze and this must be eliminated before moving forward.
I apologize as I lost connection..just a moment.
steady green is good...it means normal...have you tried furnace again?
make sure all gas back on....and gas supply to other appliances...
so the flame last until the time blower kicks on....as soon as blower kicks on the flame goes out?....Or does the blower kick on..flame starts to waver/dance then flame goes out while blower still running?
yes put covers on...is this propane?
if the gas is on...(burners) and the main blower....and there is little heat....then there are:
low gas pressure
well it is now a matter of the combination of things.
We have burner
We have blower
So the 2 things we need to deliver heat are present. So there is a deficiency in air flow (duct), dirty blower wheel, plugged ac coil (if present) or the heat in exchanger (gas pressure)
The only thing that detects temp is the thermostat.
All temp detectors in the furnace are simply limits that cut off if the furnace were too hot.
Remove the thermostat....take the wire on R and the wire on W and twist together.
Tell me if furnace runs nonstop, or turns off.
Did we check the blower wheel yet to see if clogged or if ac coil is plugged?
my guess is there is an air restriction, dirty blower wheel, plugged ac coil, plugged filter...something is restricting the air flow.....furnace overheats internally....shuts down...cools and trys again..
Can you check the inside of the blower wheel or post pics?
top section...this is a mobile or modular home install?
the main blower is behind the upper grill in door. Where the filter goes across door...the blower is behind it.
