20 Most Recent Sterling RF45 Propane Gas Heater (45,000 BTU) Questions & Answers

3 FLASHES... PAGE 21 (below) Pressure switch problem: 1. Obstructions or restrictions in appliance air intake or flue outlet are preventing proper combustion airflow. 2. Moisture or debris in tubing that connects pressure switch and draft inducer. 3. Airflow switch jumpered or mis-wired. http://homeappliance.manualsonline.com/manuals/mfg/sterling_1/tf250.html

These are the check / repair items listed for a 2 flash trouble code: 1. Gas supply off or gas supply

pressure too low.

2. Flame sense rod contaminated

or loose wire.

3. Gas valve switch is off or wires

are not connected.

4. Broken or cracked porcelain on

flame probe or spark ignitor.

clean pilot check flame sencor is clean , jump high leval limit first see if it lights , if not try low limit , check thermocouple is tight if fitted ,

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 .

If it's operating properly, is T-Stat controlled and is properly vented to the outside, it should be safe to operate all night. I suggest that you set the Wall Thermostat no higher than 50 degrees, though.

Loosen the thermocouple nut where it goes in the control valve. Re-tighten it only finger tight and with the appropriate wrench, turn it ONLY a 1/4 turn more.

If you have it to tight, it will not heat up and open the gas valve. Make sure not to cross thread it.
FYI: Gas control valves on this type of heater rarely go bad. Unless, the control knob is forced in an inappropriate way.

haven't had much to do with this type of heater but a yello9w falme is usually reducing the oxygen from the gas by the the air mixer on some flame effect fires they cover air holes on burner to get the flames yellow the only problem is they can carbon up from this in a heater you don't look into flames this may be ok but i would check the burner air mixture hole if has one but that smost likely the reason for yellow flame not blue so its probably no problem carbon in heat exchanger will make heat transfer a bit slower so probably best to try and fix

could be a leak on the pilot line or pilot or the gas valve you can check with soapy water if it bubbles it leaks or call in a gas fitter if you feel safer

Do you have an external Thermostat mounted
nearby? It could be that it is to close to the heater and the thermostat is causing it to short cycle

To Test the limit switch put the wires together (if just 2 terminal) and see if it works. If so replace the switch assuming it is not a manual reset. REPLACE the switch, Don't just leave it by passed. If it has 3 or more terminals you will have to find the wire diagram and decide which terminals should be closed and if any should be open, or if the switch has some kind of built in heater on the part.

If the same thing happens you know its not this part but something else and you'll have to get a volt meter to start eliminating whats working from whats not and when its working to get to the bottom of the problem and finding what it is.

Please if this helps you rate me as high as you possibly can. Thank you for using fix ya.

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.

looks like you will need to open machine up and locate a common, off a relay or the transformer. If unfamiliar with this stuff you will likely need some help.

Some times you can remove the bottom of the heater and light the pilot from there .

Sounds like you broke the hot surface ignitor ?? he was on about the flame sensor a rod .so replace what you broke and clean the flame sensor ,also check the pressure switch.

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. documents http://homeappliance.manualsonline.com/manuals/mfg/sterling_1/tf250.html http://homeappliance.manualsonline.com/manuals/mfg/sterling_1/tf250.html
