Frigidaire downdraft blower model pl30dd when it reaches the top after activating it it just goes down, sometimes it stays up and on after several efforts

Hi,

Please double check that the button that causes your item to move upwards isn't being accidentally pressed because this might cause the continuous motion that you're experiencing. If this does not work, please reference the troubleshooting section of the device manual for this issue. Thank you.

yes you are right..there are switches that should be detected that the unit is in its proper level ans hould stop and turn the fan on.

you may inspect the railing or where the moving part is moving to find limit switches or sliding switches or sensors..it could have been defective with oil or grease and not making contact to transfer the signal to the controller.

tnx 4 using fixya,

Sounds like the low limit or high limit is out these control the fan motor.They are usually set to kick on around 150 degrees and set to go off around 95 to 100 degrees. Over heating does happen with cracked heat exchangers and it can possibly take these two items out. Normally your furnace should run approximately five minutes or a little less then your fan motor comes on and then for cooling down burners should drop and the fan motor should run again roughly five minutes or so then shut down. Times may vary as to your settings.

If I can get the model # I can help you more with the removal and reinstall.

good day,
hope this link below will solve your problem.

Hi
Tha model is a Maytag.
There are a few things to check here, and it's best always to use the proces of elimination.
These are the things you need to check:
1.MOTOR, DOWNDRAFT
2.BLOWER ASSEMBLY
3.SCROLL, BLOWER ASSY.
4.CORD, POWER (MOTOR)

as you mention before sometime run and sometimes do not run.
youll have to start by checking those items and make sure they are not damage or obstructed. I have some wiring diagrams for that model, if you would like for me to email them to you, please let me know.
I hope that will help you

I had a similar issue with the Thermador CVS30R hood continually going up and down, and also issues with the fan starting.
The issue was found to be a loose control arm off the motor. The arm itself moved outward on the motor shaft which resulted in it missing the switches that control the hood up/down and fan start.
This was a somewhat simple fix. Make sure the hood is in the down position. Unplug the unit from power(important!). Unscrew the screw that connects the drive arm to the drive link. Unscrew the motor/control cover, then unscrew the 4 screws holding the complete motor/control unit on (2 Phillips-head screw on each end of the assembly). Pull the complete motor/control assembly out, be careful of wiring. Once out, push the drive arm on firmly onto the motor assembly and tighten the screw. When doing so make sure the 2 micro switch arms are not caught and are free to switch.
When placing the unit back in, ensure all wiring is clear from being caught and ground is reconnected. Put it all back together and done!
