blower motor relay buzzing


If the noise is "normal" it might still be "loud" if the vibration is being picked up by piping, tubing, ductwork that conduct noise and even amplify it in a building. If I put back the old board, the buzz stops. I looked up the parts you are asking about in our ICP parts program and it shows a Control Fan Timer part number 1150886. Steve. I am sorry, but we do not sell any Oil Furnace parts. I would start by having everything on and taking out individual bulbs to see if you can identify the actual source of the buzzing. Hope that all makes sense would appreciate the help. Hello, Chris, Hi Chris! My question is , does the blower fan have an override which keeps it from running until the coil is completely thawed ? . If you aren’t getting 24 volts between G and C then you might have a thermostat problem, a thermostat wire problem or the low voltage fuse on the control board might be blown. If ” emergency heat” is selected calling for the furnace it works just fine. Buzzing. Glad to hear that you found the problem and got it fixed. [Blue arrow in my photo]Buzzing heating system control relay switches also can be quite noisy. Do I need the honeywell equipment module with a newer thermostat? I hope you have a great day! Thank you.. Hi Jason! From your text I can't say what's happening in your gas fueled furnace; After a few seconds of buzzing, the red button will trip. If the voltage is below 24 volts then you might have a weak low voltage transformer, thermostat problem or a bad, loose thermostat wire problem.

When I “manually” supply 24 volts to the relay coil, the blower comes on, so blower and relay are fine.

I have a Trane Powerlink II heat pump system. However, if I turn the fan position back to “circulate” or even turn the temp down to turn the cool on the fan will once again work properly. Since you say that the motor is 17 years old I would strongly recommend a new capacitor.

Solution: Test to make sure you are getting 24 to 28 volts AC between the G (green) and C (com) terminals on you fan center or control board. If a new capacitor does not fix the indoor fan motor then I would suggest that you check with a voltmeter to make sure that the motor is getting 220 to 245 volts AC. I would like to suggest that you test down at your air handler where all the thermostat wires are joined together at the air handler. I have a simple ICP Central AC unit in the house I bought last year. He said the firebox was so plugged up that it couldn't get enough air. I would also recommend that you check to make sure that you are getting 24 to 28 volts AC between the G and C (common) terminals on your control board when you have the air conditioner on or thermostat set for the AC to be ON. You should have continuity between M1 and M2 when 24 volts Ac is applied to the bottom terminals. Hi Dennis! Has been finicky the last few years. Abnormal engine buzzing. 5. Steve, I have a Goodman 3T-16 SEER, package unit, everything has worked perfectly fine up until a few months ago, I cut the unit on and everything was running but it wasn’t blowing any air, so I turn the fan switch to on and it still wouldn’t blow, I would turn unit off back on a few times then the blower came on so once it came on with the AC I just turned the fan switch to on from auto just to ensure we would have air, as a test I turned it back on auto after a few days and when the AC cycled off and back on the blower again wouldn’t come on, so after a turning the unit off and on a few times the blower decided to come on again and now I currently have the fan switch on so it’s always running, so what would make the blower not want to cut on like it is doing, Hi Vance!
