If you have a fan blower on your heater, it may be that the motor shaft is stuck and you're hearing the motor humming. Which, if it is, will burn out the motor.
Here's a link to the Williams website. There you can download the Owners Manual for your Model Number heater. There is a good Trouble Shooting Guide in it, which may also provide more info on what's causing the humming noise.
need to go to furnace and watch it...if your hearing a hum the enducer draft motor may have failed...it should start first if there is no fault codes...reset unit by unplugging furnace or in some cases turning power switch off...turn thermostat on heat and watch unit ..the small enducer draft motor should start first the a ignitor glows and the should light...goodman units have a control board with a light on control board when it fails should flash a code and on the door or inside on lable should give you what that code is...hope this helps good luck
sounds like you may have a ceased fan get someone to look for you, but an electrical hum that is louder than normal usually means that the fan or a moving part is trying to turn ot move but can't so make's like a hum noise so seek a service agent
First check the fuse for the fan. If it makes a humming sound, check if the fan blades have jammed somewhere and being physically stopped, it creates a humming sound.Also check the insulation of fan armature to see if an of the coils have shorted out. Also dont forget to check the condenser/capacitor which initiates the rotation of the fan................sodeep
you have a circuit board acting up. Try keeping the fan in the "On" position. It will keep the blower on all the time but it may work. There is a built-in delay not allowing the unit to come on after you reset it with the thermostat, wait three minutes or so to see if it comes back on. I still suspect a bad circuit board.
Blank screen sounds like a fried thermosat. Abrupt outages can affect certain types of thermostats. Make a jumper wire and jump across R and G. See if you get any action from anywhere. If a fan or compressor kicks in you know you have a burned out thermosat...
