Question about Sterling RF30 Natural Gas Garage Heater

1 Answer

Sterling garage heater wont always light.

My heater will try to kick on 3 or 4 times. You can hear it light for about 3 secs and then shut off. It does this 3 or 4 times then doesnt try again. Then i have to reset it. It seems if it cools down it will fire right away. Say in the morning when i turn the heat up it wont have a problem, but after it runs a while and has to start up again it will go through the process of not starting. Sometimes during the 3 try cycle it will kick on, but its starting to get worse.

The flame sensor is dirty - have the unit serviced. Modern furnaces require regular maintenance!

Bought a sterling 75 c garage heater burner lights but then 24 v transformer burns out

I didn't find that model but did see a pretty standard wiring schematic for Sterling garage heaters in one installation manual. I'm sure they didn't change much. I did notice they use a 50va transformer, not 40 which is likely what is getting used now. Don't think that would fix it, just an idea. Put a 5 amp fuse inline on the red side of the secondary side of the transformer. This will protect it. I'm willing to bet the ignitor section on the low voltage common is wired wrong. Remove the tstat wires, buy a resettable fuse and install it first. Then get the fan running first. If there is a g terminal jump red to green. This is fan only, start simple, hope this helps

I have a Sterling garage furnace,pilot is on ,but main burner will not light.

Be sure you turned the Control knob from Pilot to ON. Without doing that the heater will not turn. If that's not the problem, the Thermopile may need replacing. Also, check the volume of gas at the heater. It should be a minimum of 5 to 7 water column inches. If it has a wall thermostat, be sure the wires are correctly installed at the heater and the wall thermostat and the it's turned up higher than the ambient air temperature in the garage. If this is an older installation, be sure the exhaust vent piping is not blocked.

It doesn't want to shut off and we have no heat?

when you say it doesnt want to shut off i'm guessing you mean the fan. the fans run on a timer when the thermostat calls for heat it will come on 90-120 sec.later. turn your t stat down below room temp and it will shut off in 30-60 sec.your ignitor is most likly bad. turn your t stat back up and look at it. it should glow. furnace will try to light 3 times,you may hear the gas flow for 3 sec.during this cycle. if no glow good chance that is your problem and you will need to replace carefull it is very brittle and breaks easy if tapped. be sure to turn the t stat down again or the fan will start running again.

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.
