Hello, I asked a question about exaust blower pulley coming off several times. appliance pro said to use locktite on pulley threads. i did this and it stayed on. Pulley was left hand threads. I turned drier on pulley and belt in place before locktite and pulley runs toward right hand thread which would thread pulley off, also noticed that fan turns same direction as pulley,looks like fan is turning backward,against the back of the cup of fan blade. Do you think dryer motor is running backward or is this normal. Thanks ed

1 Answer

Hello Ed. As long as the fan motor is exhausting the air out of the back of the dryer, it is normal.

I have a maytag dryer model medb800vqo. the pulley on top of blower has come off blower shaft several times in a year.i think pulley is left hand threads. I put pulley back on last night and belt back on, and turned dryer back on and pulley came off as soon as dryer started. the blower fan turns free. both the pulley and belt look fine.tightened pulley as tight as possible. I have ordered appliance parts in past, i like appliance partspro.com because you have schematics and part numbers,and parts arrive quick. thank you, ed

Hello Ed. You need to put some Loctite on it and then let it wait for about 6 hours before running.

Groundhog, While we do not have specifics on the threading, I do believe the part is left hand threaded.

Hello Joseh, If the belt is properly installed the issue will be a bad blower bearing in the blower housing WPW10256512. If it is the tub belt that is coming off the issue will be the idler pulley WPW10547292.

Chad, you'll need to check the ignitor part number 279311, make sure it is glowing a bright white. If it is ok, then test all the thermal fuses/thermostats and make sure they are closed or 0 with a multi-meter. The flame sensor will read closed as well. If all of this is good, then you may have bad coils. Hope this helps, thanks.

Tim, The pulley mtr attaches to the motor shaft and if the threading on the shaft is stripped then you will need to replace the motor of the unit.
