SOURCE: Coleman furnace problem

Sometimes people replace the blower motors with a higher horse power. Has this motor ever been changed? I believe the original should be a GE motor

SOURCE: Coleman forced air furnace blower

Rmove the two screws holding the blower in place and slide it out. With the power off, rotate the wheel and inspect for debris or an impingement. If everything turns easy, you have a bad motor or start capacitor. If you have rubbing, adjust the wheel. If the motor will not turn, replace it.

SOURCE: Sears 92 gas furnace noise when not in air handling mode

a very subtle hum or buzz is normal and is the transformer that creates 24 volt control voltage continually. some are noisier than others . sometimes a tap or bending of the transformer will tweak the metal enough to make it quieter. they can also get loud if incoming voltage is not correct. incoming 120 volts on a furnace is not usually a problem but the transformers are usually wired to the available incoming 230 voltage or 208 voltage if it is a heat pump or electric heat. If it is powered by 230 or 208 volts as most heat pumps are ,then you need to verify which you have and connect the appropriate leads from the trans former to power . it tells you on the side of the transformer which to connect to 230 and which to connect to 208. tape or cap off any unused leads.since you have not mentioned any performance problems i assume the fan does come on when called for and that it is not the loud hum you hear. switching the fan switch at stat to on should bring the fan on right away. if it doesn't then you may hear a loud hum and then youll need to check the fan motor and capacitor. but it sounds like a noisey transformer from here.

SOURCE: York P3HU Gas Furnace Blower wheel makes noise and vibrates

yes you have a bad blower wheel the fins are crimped to the disks, if you can take the blower assembly out just watch the wiring and take the motor out of the center of housing away from blower wheel and when taking out the wheel remember the diriction of the wheel

SOURCE: I have a new home 1 yr and when the furnace kicks

Check by turning the unit off and turn the fan to on. Do you hear the noise now? The noise your hearing could be coming from your combustion fan assembly instead. Newer furnaces have a in-shot burner and are nosier than the old style of heater.

Electric furnace fan works heater does not


coil could be broken. open the cover hold the door switch and look to see if the coil glows when the heater is turned on if not turn off the power then remove the coil then turn on the power and check the voltage you should get 210V A/C on a meeter if you do or yo can do this firs, check for continuity on the coil if you get continuity then check for voltage. if no voltage check the breakers or check the breakers first the electric heater needs two breaker if one is tripped you could have a blower and no heat.

Furnace kicks on then shuts off


Coleman furnaces us a temperature delay with a temperature on around 130F to 150F and off around 110F.

If the inrush of cold air cools the delay below the off temperature the fan will go off until the heater heats it up to the on temperature.

Blower motor will not come on


If the blower motor has correct voltage and not running it can be a capacitor, its about $5 to try it, otherwise a new fan motor is required. 22296134-wil0gxehsfojcry3vcxysbjd-5-0.png

Heating elements keep coming on and off after blower turns off


Yes your sequencer is the switch to energize the elements & sometime the low speed on the blower motor. It completes the 240 volts going to the elements. The sequencer turns the elements on in stages as well as the blower, & most sequencers have numbers on the side to tell what thermal disk turns on first. The blower, & one element should be wired on the 1 & 2 terminals (this turns on first when the sequencer coil is energized & shuts off last when the coil is de-energized). If any of the thermal discs are stuck closed, this will constantly energize the element on that switch.

Convert coleman eb15b to natural gas unit


Sorry there is no way to convert it to a gas unit.. The only way is to replace the furnace with a natural gas unit. You will need a gas line ran to it and a Flue. and then room to fit everything in that space.

Fan won't blow on ac, but works on furnace


The fans heat speed is low speed and the cool speed is high speed. High speed is controlled by the fan relay normally open switch, the low speed is controlled by the temperature delay or time delay.

Blower not shuting off properly


The blower is controlled in col by the fan relay, in heat by the temperature delay, if you tap the delay it will shut off usually, just replace it its not expensive.

The AC unit outdoors must be running and rejecting heat by its air flowing through it the 2 copper lines are the refrigerant lines, the fatter one should be "beer can cold" if not its low on refrigerant or not running.
