Question about Sterling RF45 Propane Gas Heater (45,000 BTU)

1 Answer

Sterling Gas Heater

Sterling RF 45 garage heater, It blows the 2 amp fuse on the 24 volt side of the transformer. When a new gas valve was installed it continues to do the same. The replacement valve is a Honeywell SV9501M, the original valve is a SV9500M. The local parts supplier says that this is an upgrade to the original.

    Thanks JB 40, you were right, the high temp cutoff was shorted to one of the heater tubes. I took a long time to find it. Thanks again.

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.

Coleman furnace dgaa077bdta

The control fuses keep blowing tells me one or more of the control that operate the control on 24 volts is malfuctioning. Most controls operate at about 5 watts and on a clamp on amp meter normally pull about 0.2 amp (p = current x voltage, 5 watts = 0.2 amps x 25 volts) I install 75 watt 24 volt transformer with a resettable overload to save on fuses. I reset the transformer and quickly go to the controls and determine the amp draw. When I find the one >0.2 amps I found the problem. The things to check is the emergency heat sequencer, fan control sequencer, reversing valve for heat pumps, main contactor on the condensing unit and any other 24 volt control loads. I have had to replace the themostat wire because the increase current for the thermostat wire can cause the entire length of wire to form a long heater and cause insulation degradationa and cause the thermostat wire to short out and blow the fuses.
Hope this helps

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

Pilot is on but thermostate will not turn it on what else can i try

What kind voltage is the heater operating on, 24 volt or 750 millivolt? If it is 24 volt check the transformer & thermostat for 24 volts along with gas valve, if it is a 750 millivolt system check the 2 wires coming from the pilot burner area for 750 millivolts, if you have a wall mount thermostat, tie the two wires together and see if main burners ignite, if they do replace thermostat. I really need more info to help you more, this unit came with two types of gas valves, a 24 volt & a 750millivolt type check name plate on unit to see which one you have.

Mr. Heater Natural Gas Garage Heater - 45,000 BTU. Power 120 volt and 24 volt good. Thermostat calling for heat, but nothing happening??

Check for a fuse either in-line or on the circuit board. There should be 24 volts going to the thermostat. If not, you have either a bad transformer or a bad thermostat wire. Jump out the terminals that the thermostat wires are connected to. This should force the unit to fire. If not, bad circuit board.

Installed dayton nat gas hanging furnace in garage and have 2 wires dont know where they go one came from the back side of the transformer it was twisted with the other wire

Hopefully there is a wiring diagram glued to one of the panels to verify but on the transformer you will have 2, 110 volt wires. One is the power coming in (usually black wire) and the other is a common (white wire) and will be connected to other common leads. On the low voltage side of the transformer one wire will go to the thermostat then from the thermostat to the gas valve. The other side will connect to the gas valve. When the thermostat calls for heat it completes the circuit from transformer to gas valve back to transformer.
