Your problem could be as simple as a blown fuse. Most R60's have a small buss fuse mounted on the Ignition Control Board. Replacement fuses are available at www.reddyparts.com . If the fuse checks OK then test to see if the control board is receiving power. If power is going in but not going out then, naturally the board is defective and must be replaced. An easy fix!

    ALSO, if your heater is equipped with a thermostat, troubleshoot the part to see if it is functional.

I have a 70 ooo btu reddy heater! When trying to start it the ignitor comes on and glows but then goes out! It's like it wants to start but it won't turn on blower and fuel! Any idea? I think it...


You have to see if you're getting voltage across the coil on the gas valve. Measure across the MV and C terminals. The HSI (igniter) will have a warm up period of a few seconds before the gas valve is energized. So get the volt meter on it, if you get proper voltage it's a bad gas valve (or no gas supply) and if you don't get voltage it's the board!

Check your conection off the board to the initor and make sure the pins in the plug are set tight with the connection on the board. If you wire nutted the wiring together for the new ignitor you installed check these connection also. Make sure all wire strands at the wire nuts are in the wire nut and not touching or arching on the furances cabinate.

No blinks normal running igniter glows gas comes on wont run


Check for 24 volts across the gas valve when Ignitor is glowing. If no, bad board. If yes, bad gas valve or blockage.
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).

f this is a metal vent 80% furnace,Turn Furnace off
and remove the vent that connects to furnace and see if it is plugged.

If this is a High Eff furnace witrh pvc vents for
exhaust and intake air make sure they are not plugged on the outside.

Turn thermostat all the way up,turn furnace off and
wait a few minutes.This should reset any control
board fualt.

Turn the furnace back on, if you have a glow coil
ignitor it should glow red and then the burners should
ignite. If this doesnt happen then:

On High Eff Furnace if the glow coil does not glow red, remove the combustion door to the burners,
turn furnace back on, if the glow coil glows and
burner ignites, you have an obstruction in the intake
air side. If it still does nothing then:

Use caution and remove the exhaust vent from furnace, start furnace, if furnace runs then you
have a problem with the vent system

Glow bar starts, gas valve opens, gas start burning in all four ports, glow bar turns off and gas valve closes. no flame roll-out is it the board bad?


Depending upon how long the burners stay on it could be a bad or dirty flame rod, read on.

Red light blinking continuosly meanig gas valve relay short how can I fix myself - furnance only blows cold air


You will need to check for 24 volts AC to the gas valve after the igniter starts sparking or glowing. If you have it but it does not open, bad gas valve and you will need to replace it. If you are not getting 24 volts after it starts glowing or sparking, you have a bad board.

My Goodman furnace wont light.


Open up the unit to get to the control board. Make a short jumper wire and disconnect the wires going to R and W terminals on the board. Connect the jumper to R and W. Depress the door safety switch. The circuit board should indicate a call for heat and the furnace should start. If it doesn't, look for a fuse that may have blown either on the circuit board or in the wiring. If the unit started by jumping the W and R but does not when you reconnect the thermostat, you either have a bad thermostat or a bad thermostat wire.

Your furnace has a diagnostic chart on the reverse of the lower panel incorporated in the wiring diagram. One blink tells you that it is a failure but wont tell you where to start looking.

Goodman GMP075-3 ignition problem


OK, if the furnace is not lighting for even a few seconds, you have either a bad gas valve, bad wire, bad control module or no gas. The pressure switch is not the issue. Check all wires to the gas valve and look for 24 volts across them when the ignitor glows and you hear the click. Then test for 24 volts to ground. It could be a bad ground wire.
