Question about Dayton Gas Furnace Heater

Open Question

I have a Janitrol Model GMT070-3 furnace for which I replaced the draft inducer on. My problem now is that the furnace comes on and the gas comes on but the ignitor does not. I looked and the indicato

Could this just be a case of the draft inducer having an air leak somewhere? I know everything has to be sealed up tight (which I thought it was). I did notice that there are only two of the three screws that connect the top of the draft inducer with the vent tube that takes the heat out of the furnace to the house. Could that one little screw hole be enough to have the furnace not light?

SOURCE: Williams wall non-elec gas heater. Black copper wire tagged thermostat?

First make sure this is a heater set up for a remote mounted thermostat. If so, the gas valve has 3 screws labeled TH (thermostat) and TP (thermopile) that's the flame sensor with 2 wires coming off it, I don't know where the goofy name comes from. there will be one screw that has both, usually the top one. Wire accordingly. The new valves have a solenoid on the bottom. this connects to the high temp. sensor up top. It has 2 wires on it, one connects to the thermostat wire, the other goes to the screw with TH and TP. Or you can skip it and connect the wire from the back of the valve to the Th and TP screw. Make sure the thermostat wires aren't pinched somewhere, thus eliminating the thermostats control.

If you intend to use this in a residential garage, you will have to use standard galvanized round pipe coming off the unit, 24 gauge will suffice, use a minimum of 6”-8” from the unit. From there you will have to make the transition to the B-Vent. Always double check with you local codes in your area.

Hope this helps.

SOURCE: I have a Goodman GMS9/GCS9 Gas-Fired Warm Air furnace and it's no

For anyone who finds this question in the future - It's the condensate drain hose for the heat exchanger.
Get a bucket and some towels handy and unplug the lowermost flexible rubber hose - if you do this right after the furnace has stopped, water will come gushing out. Mine was continually plugging up causing my furnace to stop, like yours - the L shaped plastic tube that dips into the drain trap on the outside of the unit (the thing filled with water) was too close to the bottom of the trap. I took it out, shortened it by 1/2 an inch (keep the same bevel that's on there!) and I haven't had a problem since. Blowing out the line would only hold things off for a few weeks before it started acting up again.
Cost me $90 for a service call the first time since visually it looks fine and I checked the upper hoses that go to the pressure switch :)
Learn from my service call!

SOURCE: we have a dayton gas

When your furnace starts...the Ventor motor(exhaust fan) starts up....within a short time (seconds) the Pressure switch closes proving that the Fan is indeed running and the vent is not blocked...if this doesnt happen the furnace will not poweer the ignitor or fire at all....Check the vent pipe outside and look for obstructions or dirt on the screen inside the pipe...the condensate from the fuirnace may not be draining at all...due to plugged condensate drain lines...find this tube coming out of the furnace front...bottom of upper compartment usually , and pull it off the tap....if water starts coming out then your drain is plugged downstream of the furnace.

My janitrol furnace started to make a lot of noise over the last few days. Could something be loose or does it need to be cleaned?


I hate to say it but it sounds like the bearing in the fan is going out. If your lucky there's a replacement...if not then a new furnace. You will have to have it looked at by a furnace tech.

Its too bad I can't hear the noise then I'd have a better answer for you, sorry.

Fedders gas furnace exhaust fan comes on but will not ignite


The induced draft motor you describe has a pressure switch proves the induced draft motor is running, it is about 4 inches across and silver and flat and round, it has 2 wires and a tube that atttaches to the induced draft assembly onto a barbed port, this barbed port will obstruct with carbon and needs to be cleared annually with a tiny dril bit or similar device.

Janitrol GUPS075-3 Furnace burners will not stay lit


The first thing I would do is make sure the flame sensor is clean, this is a metal rod immersed in the burner flame on the opposite side of the igniter. If too much oxidation builds up on it, it will not allow the burner to stay lit. To clean, just turn off furnace and remove flame sensor and clean with steel wool and then reinstall. If this does not solve the problem there may be a problem with the gas valve.

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

Sounds like some one needs a new induce draft fan relay, if relay is located on the main control board you have to replace control board,follow wires from inducer motor and you will find the relay. I could help you more if i knew model # and serial # of the furnace, Good luck.

York furnace model p2mpd12h06401f flashes 4 times for trouble code does'nt have code list inductor motor comes on but ignitor does'nt come on


Check pressure switch for inducer motor. If switch closes, check for crack in ignitor. If gas valve opens and you can hear/smell gas, the ignitor is bad probably. If pressure switch isn't closed you need to check for blocked vent/chimney/heatexchangers.

Janitrol/Goodman GMP075-3 Draft Inducer Fan Won't come on


most forced draft fans are powered by 120 volts . close to the fan is usually a plug that unsnaps. create a call for heat after turning off to clear safetys and see if your getting 120 to fan on initial call for heat. if you are then fan draft motor is bad, usually sold as an entire assembly replace exact as it came out. sequence of operation is..... stat calls for heat via common and white wire to furnace , 24 volts. ......board sences call and sends 120 volts to forced draft ........ motor runs and creates pressure on proofing switch,....... switch closes 24 to board and tells it draft fan is on......... board then energizes ignitor,....... after ignitior glows gas valve is opened and burner lights ........ either ignitor or seperate sensor rod tells board the burner lit........ and a few minutes later the fan comes on and hot air is blown out. if a step is missed or doesn't proof the furnace either trys up to three times to light or locks out. turning off power usually resets safetys and it will resume attempts to lite normally.
