Thanks for counting on us to help with your appliance problem. My name is XXXXX XXXXX I look forward to helping you! If you turn that fan by hand, does it feel a bit hard to turn? Is the stopping of the fan followed by a humming sound?
Customer: replied 4 years ago.

It was easy to turn by hand. and there is a humming after the fan stops


it will start to move and then stop and then start again but only moves a little bit followed by a humming sound

Okay, and the other one keeps going?
Customer: replied 4 years ago.

yes the other side works fine


however i was cooking last night and it actually completely shut off (both sides as if the power was turned off) after a about 15 mins i turned the switch off and on and then it started working again

Expert:  Kelly replied 4 years ago.
Okay, the motor is shared with both squirrel cages, so it would not be possible for one to shut off and not the other and have it be the motor. That means the squirrel cage on the loose side is likely broken where it attaches to the motor shaft and will need to be replaced. The correct blower for your model is pictured and available below.

would that blower wheel feel loose inside the cage if it was broken?

Expert:  Kelly replied 4 years ago.
It could or may just be "free wheeling" on the motor shaft, which is what I suspect is happening.
Customer: replied 4 years ago.

do you have documentation on how to take it apart and replace the wheel?

Expert:  Kelly replied 4 years ago.
Unfortunately, there is not a service manual for these models. However, the blower wheel is usually easily replaced without much disassembly by removal of one outer panel or cover.
Expert:  Kelly replied 4 years ago.

The end cap on each side of the blower wheel will come off after the screws are removed. There is not much disassembly required. Once the end cap is removed, you will have full access. The end caps are numbers 25 & 22 in the diagram below.
