It means the thermostat is calling for heat. There is something wrong with the heater, not the thermostat.

My Frigidaire Electrolux oven won't heat above 275?

Check the thermostatic valve. Prior to this, make sure that your orifice is ok and the fuel gas mixture is right. The way to check the fuel air gas mixture is to see that the flame are all blue and no orange or yellow color flame is visible. The flame should also not lift off the burner tending to lose unburnt gases to the inside.

Burner lights and shuts off 3 times and then give warning lights A and B

It depends on the model but AB on most of the AOS the A & B LED's lighting up usually means ignition/flame failure.

Ignition/flame failure:

The gas control valve/thermostat has reached the maximum number of retries (3) for ignition and is currently locked out for one hour. Cycle the power to the water heater off and on to reset.

Basic troubleshooting/solutions:

1 Ensure flame sensor is making good contact with the burner flame and ensure flame is steady. Also ensure supply and manifold gas pressures are within the requirements in the installation manual.

2 Gas supply is turned off - pressure is too low. For low gas pressure, consult with your gas utility.

3 Ensure the flame sensor is clean - use fine steel wool to clean the flame sensor.

4 Check igniter assembly plug and the socket on the bottom of the gas control valve/thermostat for good connection. Replace igniter assembly if the plug is worn or damaged. Replace the gas control valve/thermostat if socket is worn or damaged.

5 Replace igniter assembly.

If this does not apply to your model then here is a link to the instruction manuals for all models:

Pilot will lite but burner will not when you go from pilot to on


When this happens it usually means that one of the coils is defective. The burner valve is operated by three or two coils. If one of the coils is bad the pilot will lit but the valve won't stay open when the oven is supposed to turn on.

Test the coils reading impedance at their contacts. If a coil is open (shows Ohms infinity at the multimeter reading), then the coil must be replaced.

If the coils are fine test the thermostats (always reading impedance) and replace the coils if thermostats are fine. Check also pressure regulator and ensure that the flame is OK.

Other part that could cause the problem is the flame sensor. The flame sensor is difficult to test and fails really uncommonly. The sensor works in parallel with the coils. The part is tested reading Volts. Flame sensor is usually tested and replaced only when there is no other possible cause for the problem, after testing coils and thermostats and eventually replacing coils.

My house never gets above 72/72 degrees and at night its around 64/66 degrees. The thermostat is at 90 degrees. It seems like the ignitors do not stay fired up long enough. What do I need to replace,...

It could be a couple of things. without knowing the model number. Could the flame sensor not sensing the flame and cycling on and off or it may be an exhaust fan switch causing the flame to cycle on and off. watching the flame while its running might give an idea whats happening during the heat cycle.

I have a White-Rodgers Thermostat and it has the word (Filter) on the left side and a (Flame) showing on the right hand side, I'm not sure why we changed the filter two months ago. Does anyone know what...

Flame Icon is displayed when the SYSTEM switch is in HEAT position. Display "FLTR" when the system has run for the programmed filter time period as a reminder to change or clean your filter.
You can reset the counter by going inside the configuration table of the thermostat. If you need further clarification call our WR hometechline 18002842925.

On my thermostat which is a white-rodgers the flame symbol is flashing the heat is set to 68 but it stays on 66. I have a split unit Ruud. The problem happens at night when it is cold.

Is this a heat pump system? If so I would recommend switching the thermostat to aux. or emegency heat at night when it is cold outside. The heat pump will not keep up when the outside temperatures are real cold.

TB8220U Commercial Thermostat keeps running when temp is right

the temp coming out of the vent should be 20 to 25 deg more then room temp and if AUX heat kicks in the temp should be even more.
