You should check for fuel flow. Remove the top of the heater. Watch out for the fan and turn the heater on. Look for fuel spraying from the nozzle with a flashlight. If there isn't any, clean the fuel nozzle and check your fuel filter. If this doesn't get your fuel flowing, check the air pressure going to the fuel nozzle. You will need to connect a pressure guage one of the ports on the airfilter cover. The plug with a small hole in it is for adjusting the air pressure. Remove the other plug and install an air pressure guage (0-15 psi). The air pressure you need should be listed on the label on the heater. If you can't get that pressure, check the air filter. Let me know what you find if this doesn't get you going and I will give you some other things to check.

Ignition is locked out unit will not fire


Turn it off at the black toggle switch inside the front panel or turn it off at the breaker for 2-3 minutes
Then try again.
Check that flow is good, gas is on ect...
Is it saying lockout on the display?
If not then as you fire it up after cutting power keep the panel off and watch the ignition control red diagnostic light.
The blinking sequence of that light should point you in the right direction. There is typically a label that will tell you what the blinks mean.

I have a janitrol gmp050-3 and when the heat turns on, the vent blower comes on, however the burners are not igniting. i thought that perhaps the gas valve might need to be replaced. any suggestions?


After the vent motor comes on does the glow plug ignite. If it doesn't ignite it is either the glow plug or the
pressure switches are opening up. Can you take top door off, whether ignitor light or not, you should be able to hear gas going in for a few seconds. If can't hear gas, probably pressure switch.
There is a small glass window in bottom door. Can you look through there and see blinking red light, normally look up inside to see light. Is a code list inside lower door.

Carrier 48sx gas pack. Won't turn on. No smell. No igniting sound. Blower fan works. How do I troubleshoot this?


Remove the panel from the heater section, you will need to watch what happends as there is a call for heat. There may be a light on the control board that lights up or blinks to indicate a call for heat. The inducer blower (exhaust blower) will start. INn a few seconds after the blower starts, the igniter will glow orange. After a few more seconds the gas valve should open and the burner will ignite. If the inducer does not run, you may have a bad motor or control board. If the igniter does not glow, you could have a bad pressure switch, bad pressure switch hose or a broken igniter. If the gas valve does not open, you may have a bad control board or bad gas valve. If you get no light on control board, bad fuse, bad thermostat or bad control board.

Heater will not start


Does the blower motor start when you plug it in/turn it on? It may take around 5 seconds if your heater has a HSI(hot surface igniter). If it does you need to check the igniter and the fuel flow. Either way, remove the top of the heater. You will be able to see the fan, igniter, and fuel nozzle. Turn the fan by hand to see if it turns freely. If it does, watch out for the fan and turn the heater on. Look for the igniter to start sparking (spark plug type) or glowing (HSI type). Next, use a flashlight to look for fuel spraying from the nozzle. If fuel isn't spraying, try cleaning the fuel nozzle and check the fuel filter. Watch out for the HSI, if you have one, they are very brittle and easily broken. If you still don't have fuel flow after cleaning the nozzle and the fuel filter, you may have an air pressure problem. Let me know and I will tell you how to check it. Don't forget to rate the answer if it works.

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).

Dependable ninety two blower comes on no igniter glow gas flows


if you dont see the glow of the ignitor it is probably bad . you can check with a meter that has an ohms scale, unplug and test ignitor side OL would be a bad ignitor 45-110ohms ok.

Ignition failure code on


Sounding like a flame proving device is failing to sense flame. Try to clean the device with some steel wool. It is located right next to the last burner looks like a thick wire. Take the steel wool and gently rub the carbon that has built up off. Should only take 4 or 5 strokes. Let me know it that did it. Ken
