My dryer won't blow air. It has been slowly dying for a few months but now the blower just won't start. It would blow for a period of time and then stop working, on and off.
I ran the dryer diagnostic and it told me the obvious: your blower motor isn't getting up to speed.
I just replaced the blower motor in my infinite wisdom and am still having the problem.
I feel no air coming out of the dryer. When it does blow it gets hot though, so I don't think anything heat related is the problem.
Also the drum motor is working perfect.

Any direction would be greatly appreciated, thanks!

Edit 3: Also it has not been responding too well to pushing the power button. Sometimes it will turn on and sometimes it will take a few minutes of me pressing the button.

The blower motor is a DC, variable speed motor that operates at different speeds depending on air temperature and venting back pressure. If the blower is running below 1000 rpm, the dryer control turns the heater off. So, if your vent has excessively high back pressure, this could confuse the control and cause it to turn the heater off. Try running the dryer with the vent disconnected from the back and see if the heating cycle improves.

Thank you so much for the response Fermented. I posted that there is no air coming out of the dryer. I should have clarified to say that there is no air coming directly out of the back of the dryer.
I can get the motor to blow air if I run it for like 5-10 hours and then it will work for a few loads but I can't run it that much and need to depend on the dryer of course.
Currently the brand new blower is in, I need to pull it out and return/resell it.

Thanks again! And any additional suggestions would be greatly appreciated!

Okay, that clears things up. Since you've already replaced the blower motor, that only leaves the inverter board as the problem. Come git you one ==> http://www.repaircli...er=DPGT750EC0PL

If it doesn't fix the problem, return it for a refund!
