Hello, if the motor is getting 115 volts and buzzing than it must be replaced. Most likely the bearings on it are shot, also try ohming out the motor by turning off the power to it and reading the resistance at the motors terminals, you should get about 11ohms. Let me know what you find.

    Hello, what would signify a broken motor? I am measuring the resistance at ~5 ohms. Thanks so much for your help!

    If you are receiving power to the motor but it is not working, this indicates the motor is shot.

Goodman furnace wont start only makes buzzing sound


I assume this is the blower motor that is buzzing? Wild guess is bad bearings. Looks like a well used motor. If me, I'd replace the motor, and should have a warranty for a few years. If this is too much for you, get your friendly furnace dealer to replace it.

If the pressure switch fails to close is this because of a bad switch or inducer fan motor? goodman model gmp100-4


Do not assume that the pressure switch is bad nor the vent motor. The first thing to check is the vacuum hose from the pressure switch to the vent motor. Sometimes they get moisture in them and sometimes they get clogged in the start tube on the vent motor. Take a small needle or paper clip and clean out the start tube on the vent motor. Check the hose for dry rotting or leaks. Cut the ends back about an 1/2" if you have enough hose extra and then re-connect. Next step is to check your flue pipe for a restriction like a birds nest or a wasp nest in the outside termination point. Then to eliminate the vent motor from the equation, take the vacuum hose off the vent motor start tube and with the furnace calling for heat , **** on the hose to keep a constant vacuum on the pressure switch. Watch the ignitor glow or spark ingition start to spark. make sure it lights the burner runners and all burners are lite. usually the ignitor is on the first burner and then there is a flame sensor on the last burner. If the flame does not ignite to the last burner the flame senor will kick tell the control board to turn off the gas valve and shut down. If this happens pull the flame senor out with a 5/16" nut drive and clean lightly with sand paper and re-install it. Start the process over and you should have sucessfully fixed your furnace. If the constant vacuum does not bring on the ingnitor replace the pressure switch.

Heat not coming on carrier gas pack code 31


code 31 indicates pressure switch did not close or reopened during the heat cycle....1st thing to check is the inducer motor,,this is a small motor that turns a small blower wheel that draws the exhaust gases through the furnace and blows them into the vent pipe....1st locate the inducer assembly,,most easily identified by the small plastic fan blade that cools the inducer motor as it runs..1st turn off tstat and turn off furnace power switch..then turn on furnace switch,then set tstat to heat,set the temp above room temp by 5 degrees...remove the furnace front cover,locate the inducer motor,,if it isnt turning,but is warm or hot after a minute or so,likely the inducer motor is bad..if it isnt turning and isnt warm after 1 minute,then likely the main control board is bad,,not turning the inducer motor when it should,,,,,if the inducer motor is running,,then the pressure switch isnt closing,, could be a bad pressure switch but more likely there is a problem with the venting...some possible problems that would cause the pressure switch not to close in an 80% eff furnace [metal vent pipe] are: [1] a blockage in the vent pipe,base of chimney,dead bird at the furnace where vent connects to furnace or down inside the inducer assy,accessed by removing vent pipe from furnace....if all clear the chimney could be blocked up inside,,is the draft good when vent is removed from base of chimney?..if furnace is a 90%+ type [pvc plastic vent pipe],,then check the intake pipe at the furnace by removing it where it attaches to top of furnace..is the intake clogged with anything?..then check the intake and exhaust pipes outside for blockages,,including ice/frost/snow at the exhaust pipe outlet..

Heat Starter motor constantly running when ac is on


By saying the heater starter motor I guess your taking about the combustion blower( the small motor that vents to chimney) If it runs during the A/C cycle then the main circuit board is bad.
