SOURCE: Not sure what blower motor to get for my furnace

The real relevant info is 1/2 hp, 1050 rpm, 115 vac, 1/2 inch shaft. Bring that info to any HVAC supply, any appliance parts, Graingers etc. and they should be able to match it up. I just went to the Graingers site and you can order one for $87.50 plus shipping. lease give me a good rating for getting this info for you. Thanks.

Cleaning the flame sensor has nothing to do with blower motor not turning on. You either one of the following problems 1 bad cap for motor. 2 bad motor. 3 bad limit on blower housing or 4 a bad board. You will need a volt meter to check for these problems. Try seeing if the fans runs with unit of and fan switch turned to on. Also does motor hummmm. Is motor cage free ( can check by manually turning) If motor doesnt humm and the cage is free wheeling then you will need to find out if you have power going to the motor. If you find out that you do then you will need to change blower motor. If you do not have power then you will need to check limit with continuity tester on volt meter. If that checks fine only 1 thing can be wrong and that is the board.

SOURCE: i need to change blower motor

See if you can move it freely by hand. If so, change the fan capacitor. If tight, try oiling the motor.

SOURCE: Need original blower motor and cap. specs for Ruud Deluxe 90+

The motor specs can change from time to time depending on what the manufacturer has in mind.

If it has locked up check first and make sure the squirrel cage fan has not moved and is binding on the housing.

If it is clear to turn and wont turn,, the bearings must be bad, and this is probably NOT a problem with the motor being "wrong". Its just the way things are made.

Contact a RUUD distributor for the specs you request.

SOURCE: RUUD UBHA-14 J11SFJA air handler. The fan (blower) doesn?t runs

Absolutely, however, you want to properly diagnose the reason why the fan is not running. It could be a less expensive part than the fan motor itself.
First, check to see if you have the proper voltage going to the motor. I believe your motor requires 240volts ac. If you do not have 240 volts, you have a control problem.......either the thermostat is failing to close R & G or your blower relay may have failed to close the contacts necessary for your fan to operate.
If you have the voltage, then you want try spinning the blower wheel with your hand. Does it spin freely? Is the motor warm/hot? If so, turn everything off for an hour or so. As soon as your energize it, try spinning the motor with your hand again.....if it spins freely with no resistance and then starts running by itself, the problem is the run capacitor (approx $20.00 depending on where you purchase it from). If there is resistance when you try to spin it, the problem is most likely with the bearings and you will need to replace the motor.......if you have to replace the motor, go ahead and replace the capacitor also, making sure it is properly "matched" with your new motor.

I hope you find this to be very helpful to you, moving forward. :-)

Keeps shutting down and E-1 appears


You don't mention brand name and type of unit. But E-1 means for 3 problems.
1. Indoor room sensor defective replace it. 2. Indoor blower motor mechanism blocked. Check and rectify by replacing bearing or motor. 3. No power sensing to Blower motor from your PCB. If yes, replace PCB.Helpful?

Im looking for a parts list and manual for an american standard system as well as an indoor blower motor. model # wcc030f100bb


Instead of looking for an OEM motor which can cost an insane amount of money...

try taking the information off the motor itself and taking it to a part supply house or motor shop. i.e. an 875RPM 1/4 HP 208 V 1 PH motor with a 1/2" shaft.

Maybe taking the motor itself to the parts house or motor shop will get you further than internet searching a blower motor part number. These systems are designed so that universal parts can be put back in place....at least most of them.
