Question about Heating & Cooling

1 Answer

I have a maytag 92+ upflow 2 stage furnace. Program calls for heat at 6:30 am. Temp comes up to satisfy stat. Then inducer motor restarts and runs continually 2 blink notification occurs. This tells me blocked condensation line. Investigation shows line is clear except for a liitle brown water. Any ideas?

The sensor might be defective and giving a false signal. Also when the unit shuts down they often run a larger shot of condensation out, this maybe tripping the sensor moentarily and giving you the false reading. Check that the line is not partially blocked making the condensate run slow and backing it up for just a second when it dumps after a cycle.

Goodman gph1348m41ac unit is blowing cool air in heat mode with mid 30s ambient outdoor temp. I turn it off then on and will usually blow warm air but this cycle is becoming more repetitive. any expert...


A heat pump on the optimal heating day (about 50 degrees ambient) will only deliver approximately 85 degree air as compared to 125 degree air from a fossil fueled furnace. The colder the outdoor air is the less heat there is available to be transferred to the living space. At 30 degrees, the heat transfer capability is getting close to negligible meaning the run cycles will be approaching continuous and eventually as the heat pump along cannot maintain setpoint, the outdoor stat or stats will bring on auxilliary heat in the air handler.

If your ambient temp is below the 'balance point' of the heat pump, the house temp will drop a little lower and most times energize the heat strips through the outdoor t-stat. Your outdoor stat could be set too low for the heat pump to carry the structure all the way down to the balance point so when you turn it off and back on, the lower indoor temp automatically brings on the heat pump plus a heat strip or two, thus the warmer air. Second stage on the stat satisfies due to the heat strip, drops them out of the circuit and the heat pump is left running on first stage heat delivering the perceived cold air.

Your outdoor stat could also be not functioning correctly and not allowing the heaters to come on until the system is turned back on reestablishing the two stage call for heat.

Tons of possibilities and not enough room to list....

If I remember correctly, there are dip switches on that control board that can be set individually. It is possible that it is just a setup issue. The switch positions should be explained in the installation instructions. I know that some Goodman and Amana two stage furnaces can be controlled by a single stage thermostat, but the dip switches have to be set properly. If the switches are set correctly the furnace will run in low stage heat for approximately 5 minutes and if the thermostat hasn't satisfied yet, it will kick in to high stage heat. I hope this points you in the right direction!

How do I wire a induce fan motor


Induced fan motors on older units are wired through the high limit safety on the stack - in series. When the furnace calls for heat, the induced fan motor comes on and after a time the furnace will light.

Older units have a temp switch in the stack that rotates to bring on the burners and blower motor. . When there is a call for heat, the induced draft fan motor comes on and then the burners will light.

After the heat exchanger is warmed up the limit switch will bring the blower motor on. That's basically how it works - there are two circuits - one for the induced draft motor and the burners and the other for the blower and high limit.

New units have a plug on the board you just plug in.

Carrier Furnace won't start up


Sequence of events: call for heat at T-stat, inducer motor turns on, negative pressure created in heat exchanger closes pressure switch, pressure switch control wire runs through all safety's (these must all be in closed/safe position) if ok then glow plug lights. Time delay then gas valve opens, flame verified by "flame rod" t-stat = :)

How do I troubleshoot a goodman 2 stage that always starts at high stage


It wouldn't be stuck if that's the case the valve would never shut off. Sometimes those 2 stage heat thermostats stats call for 2nd stage if the room temp drops more than 2 degrees. Easiest way to check is take the w2 wire off of the tstat and try a call for heat. If the furnace kicks on both 1& 2 stages then its either your wiring on the fan board or a dip switch setting. If it kicks on 1stage then it's your thermostat.

I have a Arcoaire Gas Furnace (Model# GNJ100N12A1), that will not fire up. It has a White Rogers Digital Stat. First the Stat seems to be faulty, since it reads 70plus in a house that has a temp of 30...


Sounds like a faulty board. shut the power to the furnace off for a minute then turn it back on. Make a call for heat at the thermostat. The inducer should start and close contacts on a pressure switch . Once pressure switch closes the hot surface ignitor should glow red. Then the gas valve will open when the gas valve opens you should get fire till the stat is satisfied. If your concerned it is the jump out r to w on the board this will eliminate the stat. If you to reset the rollout switchs 3 timesyou're getting flame rollout and you either have a cracked heat exchanger or blockage in the exhaust piping or a bad inducer motor. Keep me posted with what you find!

Will the inducer motor stay one oce the blower comes on in heat cycle


Yes, the inducer will run as long as T-stat is calling for heat.

Goodman GS9 propane furnace inducer motor runs continuously


it sounds like the low temp limit switch, the one that cools the furnace down with the burner off and the thermostat open, when it cools to a point the fan stops, the other switch in burner area turns burner off/on, hope this helps

GMPN 100-4 furnace. Blower motor runs when not calling for heat.


The board is bad. The unit thinks a flame is present, so it tells the blower to come on. Replace the board.

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.
