"Resetting the Temperature Cutoff Switch

This unit is equipped with a thermostat which controls the temperature
of the room by turning the heater on and off. The heater is protected
with a safety device to prevent overheating. Should the heater
overheat, an automatic cut out will turn the heater off and it will not
come back on without being reset. It can be reset by switching the
Main On/Off Switch to off and waiting five (5) minutes before switching
the unit back on."

SOURCE: windshield wipers don't move, but hear motor running

check the nuts on the wiper arms and make sure they are tight. If the nuts are tight then a linkage on the wiper transmission probably came loose or broke. You'll have to pull some cowling off to access it.

Coleman mach furnace wont stay running. i turn the thermostat down until i hear it click, then i turn it back up to get the furnace to kick on.works sometimes and sometimes not. blower will always kick on...


Hi, I don't know if you are still having a problem, but it sound like the flame sensor on the unit is dirty and need to be cleaned. If it has a automatic pilot, it will have a flame sensor. Its made of porcelin with a metal rod coming out the end, laying next to the pilot flame. Just 1 screw holds it in place. Remove it and clean the tip with steel wool or a piece of sanding cloth. If you don't have this set up, I would need more info on the unit, model and serial number. You may also have a faulty thermostat, but I do believe it is a flame sensor.

Fan is blowing in furnace, thermostat raised 10 degrees over ambient temperature and not heating home. Red and green lights blinking intermittently on control board.


Cycle the power first & see if the furnace goes through the normal sequence of order. On a call for heat, the vent inducer motor should turn on and the pressure switch should prove negative draft in the heat exchanger. the board then should power the ignition phase whenter it is hot surface ignition, or spark, you should hear a spark or see the orange glow of the ignitor & the gas valve is timed to turn on. If you have proper gas to the furnace, it should allow the gas to flow through the gas valve & ignite the flame. Once the flame is ignited, the romote or local sensor should sense the flame & the blower then kicks on from the time delay in the board. If you don't have any ignition, then something is wrong with either the ignitor, ignition module, pressure switch, or you have a manual limit that is tripped(this looks like a small 1/2 inch disc with a reset button on it) If you have ignition & the flame lights, but drops out, then your flame sensor is dirty & needs a touch of sand paper to clean it up(this looks like a 3 inch metal rod opposite of the ignitor) Make sure your power is off when you clean the sensor if you need to. Also if there is no ignition & the vent inducer motor is running... if it is hot surface igniton, there is a molex plug on the leead wires to it- disconnect & check continuity- should be under 110 ohms.

I have a Rheem furnace rglh-10nbrjr that motor runs but flame does not light. If I turn up thermostat, the fan comes on and I hear a click after 10 or 15 seconds. I see no spark or anything from electronic...


Hi, you shouldn't smell any gas until the pilot flame is etablished. The sequence of operation is the small inducer motor will start on a call for heat, Then on the motor you should have a poly type tube, clear, that runs over to a pressure switch. It is a round silver part that the hose connects to, The pressure from motor closes a set of contacts and you will hear a click. This is telling the electronic ignition to start to spark and light the pilot or hot surface ignitor, which ever you have. If you have no spark and the pressure switch is closed, you have a faulty ignitor board or module. To check the switch, it will have 2 wires going to it. Just take a piece of insulated wire and touch across the 2 terminals. It should fire up. If not, the module or board, ignitor has failed. You will need to take all of the numbers from it amd go to a appliance parts house to get a new one. Don't forget how it wires back in, or you will have more problems.

Fan comes one, should hear whooshing of ignition,


On a call for heat, the 24 volt thermostat sends a signal to the control module. The control module will indicate a call for heat with a light on the control either blinking or remain solid depending upon model. The inducer (exhaust) blower will purge all gasses from the furnace and pressurize a pressure switch. Once the pressure switch tells the module to continue, the electronic ignition will energize and send 120 volts to the igniter. The igniter will glow and you will be able to see it if viewed thru the small inspection port. Once the igniter gets hot enough, it sends a signal to the module opening up the gas valve (24 volts). Either a pilot will come on or the burner tube will ignite then spread the flame to all burners. Lastly a safety sensor will be looking for a certain temperature within a few seconds and the furnace will continue to operate and the room air blower will turn on in a minute or two.

What could go wrong? The unit will not run if there is no signal from the thermostat (bad thermostat or broken wire), the control module does not sense a signal from the thermostat (bad control), the inducer does not energize (bad motor), the pressure switch does not close (blocked vent piping, bad switch, plugged condensate hose), the igniter does not energize (bad control, bad igniter), the gas valve does not open or there is no gas (bad gas valve, broken wire, no gas), the pilot does not light (dirty pilot), the burner does not light (bad burner, plugged orifice, not enough combustion air), the flame does not spread to each burner (bad flame spreader, dirty flame spreader, more bad burners), the flame safety sensor does not detect flame (dirty or bad flame spreader, bad flame sensor, broken wire, bad control), or the room air blower does not energize (bad fan motor, bad control).

Since you have 24VAC, put a jumper between “R” and “W”, you should hear a relay click from the control board, this is for the inducer motor, if you don’t have 120VAC at the board, you have a faulty control board, it’s the same scenario if you do NOT hear a click.

Hope this helps
