I replaced a motor last week and i didn't double check the direction. Fortunately my friend Larry lives next door to his mother and is a little handy and reversed the motor himself. To do this turn off the power. Look for the two crimps that don't have the main power hooked to them, and reverse where they are plugged onto. turn the power back on.

SOURCE: My blower motor doesn't blow air out the air ducts why

Check for a frozen cooling coil. Turn the fan to the on position at the thermostat and the cooling to off. Your cooling coil may be iced over. Allow it to run in the fan only mode until the coil has had a chance to defrost. At the outside unit you may see the large line is frosted. This is the visual indication for a frozen coil. When you return the A/C to cooling use it with the fan on while in the cooling mode.

SOURCE: blower motor in home air conditioner does not work

The most common failure for this problem is either the start/run capacitor or the fan motor. IF YOU ARE NOT experienced with electricity then I would strongly suggest hiring a technician. The volts are 220 with a potential of 50 amps in a common residential unit.

If you are knowledgeable in this area then make sure the motor has volts to it. If it does have volts and does not spin, it is bad. You can sometimes tell by feeling the motor it will probably be very hot. The compressor will eventually shut itself off when it over heats. It usually will restart after it cools down(sometimes many hours). The motor and capacitor are pretty generic and can be matched up at a local Grainger store or whatever Retail, specialty store that you have in your area.

I hope this helps:)

A/c blower turns slow and makes puffing sound. bryant 80% avac system.little cold air from vents


Hello, replace the capacitor as when there are storms sometimes they can cause a voltage spike and damage the capacitor. The capcitor will be a round or oval metal looking can next to the motor. When the blower motor runs slow the coil can start to freeze due to lack of airflow and this is why little air is coming out of the vents. If the capacitor does solve the problem then the motor will have to be replaced.

I would first eliminate one furnace from the equation, the exterior wood furnace... turn its tstat down. Will the gas furnace then operate normally? Can you run the blower manually, as in summer mode? Make sure your filters are clean also... that can sometimes overload the blower.

31 PRESSURE SWITCH DID NOT CLOSE OR REOPENED - If open longer than five minutes,
inducer shuts off for 15 minutes before retry. Check for: - Excessive wind
- Proper vent sizing - Defective inducer motor
- Low inducer voltage (115VAC) - Defective pressure switch
- Inadequate combustion air supply - Disconnected or obstructed pressure tubing
- Low inlet gas pressure (if LGPS used) - Restricted vent
If it opens during blower on-delay period, blower will come on for the selected blower

Carrier Furnance Fan / Blower Doesn't Start (Model 58GP-125-GA)


sounds like a bad capacitor usually screwed to the blower housing (round or oval shiny can)
this gives the motor a kick start)
depending on the motor there is usally two brown wires that go to it
check the mfd rating on it probably 5mfd and replace it with a matching one
its a very inexpensive part

Blower not working


check your thermostat first to see if it may need batteries (some of the newer types of thermostats requir batteries to work properly, These are the digital types) If there isn't any problems there then check the electrical panel to see if there is a breaker for the furnance and if it has been tripped. If not, go to the furnance closet and check to see if the unit is plugged into the electrical service for the furnance, if it is plugged in I would suggest checking to insure you have the correct voltage comintg into the system. If so and you do have correct voltage coming into the furnance then you have a bad blower motor or blower motor capacitor. The capacitor can be checked with a meter that checks capacitors I would have this checked first and then the motor However if you have to replace the motor at that time I would replace the capacitor. Good Luck hope this helps

No heat through vents


Does your condo have more than one thermostat? if so there are powered dampers that open and close to direct heat where it's being called for. You may have dampers stuck/inoperative.

My heater turns on the gas starts but then it shuts down


Try to locate the red and white wires either behind your thermostat or on the furnace itself. Jump them out and see if the furnace stays on. If you do it at the furnace you will need to hold the door switch down. If it runs fine, you have found your problem (the thermostat) if it goes out again, the furnace will display a number of blinks on the circuit board. Look on the reverse side of the furnace access door and there should be an Error Code chart to get you started figuring where to look next.

Goodman Heater Blower Not Coming ON


I am experiencing similar issues..the blower you hear is the vent blower probably..mine does the same..it vents the unburnt gas out of the vent pipe thru the roof. you should be able to run the fan manually from the thermostat to at least check and see of the blower works atl..at least it will let you know if the blower motor is ok..I have had to replace the control board once and I think it is the culprit again..mine is sooooo erratic.
