It sounds like you have a short somewhere. Possibly just a pinched wire? Scroll to the bottom of this page and download the installation / troubleshooting guide for more information.

Check to see if you are getting power to the ignitor...

if your getting power and it is not glowing then the ignitor is bad... if there is no power then it is the controller...

My green led is flashing twice on my sterling tf250 furnace and it not firing up. I was wondering if theirs a trouble shooting guide for these heaters that might help me out?


Yes... 2 flashes... An ignition failure... (page 22)

Most commonly a cracked ceramic IGNITION element...
(less likely low or no gas... still less likely... wires open).

Try removing power and restoring.

Listen for the pilot valve to operate...
located in bottom RIGHT of fan side.

Clean flame senser first , try jumping out pressure switch , or try jumping out hi leval cut off or low leval cut off , could be air in gas line .

Green light flashes when i try to start my TFO 75 garage furnace


Looked at Sterling garage heaters in general. 3 blinks read pressure switch. You should have code chart on furnace door. Pressure switch symptoms are blocked vent or moisture in small hoses connected to pressure switch or bad pressure switch. If small hoses have sags take off one end and dump or both ends and blow through.

I have an older sterling gas furnace hung from the garage ceiling that cuts out intermittently . It does not trip the breaker but often if I reset the breaker at the fuse panel box it will start up.


Hi,
The heater is going into "lockout"... it should be flashing a code on the ignition control that will tell you why it went into the lockout condition...

My guess would be that the high limit switch is bad or going bad and it is cutting out when it shouldn't be... or the flame sensor is loosing contact and cutting the burner off...

You could try to clean off the flame rod with a soft cloth...

Turn on green light flashes


Count the flashes before a pause. A steady on is bad ground or loose igniter. 2 flashes is either low gas pressure, bad flame sensor, gas valve wires loose or bad ignitor. 3 flashes is a bad pressure switch, or blocked vent. 4 flashes is a bad roll-out switch or open contact. 5 flashes is bad wiring to gas valve or flame sensor, 6 flashes is either a bad control board or bad thermostat.
