Question about Goodman Air Conditioners

Goodman: My Power Venter (aka Heat and Draft Inducer) won't start

FURNACE:
Made by: Goodman
Model #: GMPN080-4

THE POWER VENTER (this is what the Goodman manual calls it but other websites refer to this as the Heat or Draft Inducer):
Made by: FASCO Industries 70219565
Type: U218
Volts: 115
RPM3400
Customer Part #: B2833001S

I have been troubleshooting this all day and this is what I have learned:

The Thermostat is ok.
The Indoor Blower (Main Blower) is ok. I can turn on just the fan from the thermostat and it turns on.
Everything was working fine and then something happened. I have not moved any wires or made any changes.

Here are the sequence of events:

I turn on the heat from the thermostat.
The Thermostat clicks telling the furnace to turn on the heat.

The furnace has a humming sound coming from it. This is the Power Venter/Heat Inducer trying to turn on. The indicator light blinks three times. The panel explains that this means:

"Pressure switch failure to close. check venter, pressure switch, vent blockage"

The humming sound will stop and then begin again but nothing happens. Also during this time a burning smell is coming from the power venter. It smells like burnt plastic but I am not sure what it is.

I attempted to move the fan blades on the Power Vetner with a screw driver but the fan blades are not accessible.

My next step is to remove the Power Venter, open it up and clean it.

Any suggestions will be greatly appreciated!

    Thanks for the feedback. I solved it! The problem was that the fan was stuck. I uninstalled the power venter and stuck my finger into the fan and dislodged whatever made the fan stick. It took quite a bit of pressure. After that it spun freely. I have no idea what was causing the fan to be stuck so hard. I reinstalled the power venter and everything works. Does anyone know what would cause the fan to be stuck?

  • MikeS5643 Dec 04, 2008

    I thought I did but the problem continues to exist. This time I removed the power venter and the fan is rubbing against the case therefore there is some friction which is preventing its from spinning freely. There is enough friction to not allow it to start spinning when the thermostat asks for heat.

    Any ideas how I can fix this? Can I take it somewhere and have them repair the fan. The motor and everything else is fine.

The power ventor most likely needs to be replaced. But be advised. Goodman normally will not sell parts to anyone but a certified technician. I had to show my masters certificate to buy parts from their outlet. This is a part that has a high rate of failure.

The fan blows but the igniter does not light.


When a furnace has a bad ignitor what I see most of the time is the following sequence of operation:


1. On a call for heat
2.The draft inducer motor starts.

3.The pressure switch which has a small plastic or rubber tube attached yo it senses the negative pressure produced by the draft inducer and closes.

4.The draft inducer runs for 30 seconds to a minute before you hear the gas making a hissing sound. The ignitor did not glow,therefore the flame sensor (a small metal probe about 1/8" in diameter, with a white porcelain base) does not sense the flame, so after 8 to 10 seconds the gas hissing sounds stops with no ignition of gas to heat your home. Your furnace shuts down and goes into a lock out condition until you turn your power switch back off and on again. Then the sequence starts all over again with no ignition of the gas. Solution:You probably need to purchase and install a new ignitor. I would suggest that you inspect your ignitor closely for cracks. Please Make sure you do not touch the ignitor with your bare hands. If you do not visually see a crack, then you could possibly have a furnace control board problem or a bad limit switch or rollout switch problem.

Hello there, I have a Goodman GMH951155DXAC furnace that I got in 2007. I have the following problem for the last 4 years: When the thermostat calls for heat the induced draft motor comes on and 30-40...


With furnace OFF ,Disconnect the top of the hose that leads to the
Bottom of Daft inducer Box, Now blow into it water will come out
of the drain hoses "condensation " this will shut the unit down if not drained. There must be a Trap on the side of the Furnace with water in it , to have positive presure to suck out condensation. This will fix problem. some installers forget to install this Trap that comes with Unit.....!!!! A little item
that will shut the whole system DOWN. :o)

My furnace wont lite


Problem: Your furnace will not ignite the gas to produce heat for your home.The following is the sequence of operation and probable cause:


1. Thermostat calls for heat. 2. Draft inducer motor starts. 3. Pressure switch attached by a small plastic or rubber tube senses the negative pressure produced by the draft inducer and closes. 4. Draft inducer runs for 30 seconds to a minute before you hear a gas hissing sound. The ignitor did not glow, the flame sensor (a small metal probe about 1/8" in diameter, with a white porcelain base) does not sense the flame, so after 8 to 10 seconds the hissing sounds stops with no ignition of gas to heat your home. Your furnace shuts down and goes into a lock out condition until you turn your power switch (or circuit breaker ) back off and on again. Then the sequence starts all over again with no ignition of the gas. Solution:You probably need to purchase and install a new ignitor. I would suggest that you inspect your ignitor closely for cracks. Make sure you do not touch the ignitor with your bare hands (use gloves). If you do not visually see a crack, then you could have a furnace control board problem or a limit, rollout switch problem. The furnace's control board might not be supplying the voltage to the ignitor. If your furnace lights and the gas stays on for 8 to 10 seconds, then shuts right back off, then you need to clean your flame sensor with light sand paper or steel wool. You might need a new flame sensor, but most of the time they can be cleaned an will work well after cleaning.

I have a bryant 90 i and when it calls for heat the inducer doesnt even come on


The first thing I would do is to verify that you have power to furnace. Check breakers and there may be a swith with a fuse in it mounted to side of your furnace or close by check fuse. You can use volt meter or test light to check for power. After you're sure you have power and thermostat is calling for heat if draft motor does not start you need to replace it. Draft motor is the first step in furnace start up.It should run for 30-45 seconds.then spark igniter or hot surface igniter should light pilot. It should stay on for about 20 seconds then burner should light. After burner lights the main blower should come on in about 2 mins. If you can get draft motor to run then procede to next step. Hope this helps you. Thanks

Heat does not work when thermostat calls for heat...


This is a safty limit switch. Find two wires that are going to the inducer or combustion blower that terminates to a small disk about the size of a penny. In the middle of those two wires should be a small button. Push firmly down thus reseting the switch. This should do it. It could also be the pressure switch but I have never heard it called that before. If the first doesn't fix the issue. Remove the small tube that runs from the inducer to a black or silver disk, blow out and draw in air until you hear clicking noises. Sometimes they can become stuck. If that doesn't work, remove the other end of the tube from the pressure switch and blow through it. Sometimes debris can clog the entrance to the pressure switch as well. Hopefully this will solve your problem. You can have a bad limit or a bad pressure switch. In this case you will probably have to call someone out.

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.
