Want to use Micrwave fan as just a blower

Hi
I want to use a OH Sung 6549W1V006T as a regular blower. Looking at wiring diagrams - it looks like I need a separate capacitor -- Can I get away without using the Capacitor?
Thanks in advance--
- Eric -

please see the next topic:
Microwave Runs, but no Heat OK, get ready, this micrwave oven repair can take some time. This is where you must be able to read a wiring diagram and do some "live" checks on parts. First easy check is to make sure power is coming off your control board at the MW relay. Make sure of the wires and test here, if you have 120 volts at this point, you have ruled out a lot of parts that could be the problem. You have now ruled out any switch problems, control board problems, or a thermostat or 2.
If you do not have power from that MW relay on the control board, you must trace the wiring back to see if the proper voltage is going through your switches, any thermostats, and arriving at your control board. Your wiring diagram on your sheet will show you where and what to test. Below is a general switch test troubleshooting guide.

I have a kenmore microwave hood combination model 721.80019. The blower unit has recently started squealing when we run the microwave. I am not sure if it is rubbing up against something or not. Is there...


Hi,

I just found out the same problem with mine.
I think the bearing of the fan motor has problems.
I took it apart and now looking for a used or new fan motor unit.

The micrwave warm fan not working?


Hi, I have to assume that all other funtions are normal. Most of the time when only the fan stops working that 2 bearings maybe even just one has siezed. Rarely do the windings fail but occassionally they do.

If your up to the task WITH POWER OFF you can open the chassis ground across the large capacitor and then see of you can turn the fan by hand. If it is sticking you can actually disassemble the fan motor and use a small piece barrell rolled and OILED paper towel to clean the bearing surfaces and the armature shaft.
If it turns by hand with little or no resistance then the possibility of a fan winding failure exists.

In that case disconnect ONE of the wires and read across the coil. "Resistance" should be less than 10 Ohms. If you get no resistance then the winding is open.

Lastly there is that rare possibility that the control board or relay that controls the fan has failed. This is not an expensive repair (except for the control board) but the longer you use it with the fan not working the shorter the life span of your Microwave.

I think you will get off with a reasonable repair expense if you can not do it on your own.

Microwave blower motor wiring


I have an OH SUNG from a different model micro and have hooked it up every which-way I could and some how managed NOT to mess it up. I finally realized I needed the 6 microfarad capacitor across the RED and YELLOW. Works like a champ. ****** can move some air btw. I am thinking about thowing this puppy in my PC when I overclock it...

Maybe your VIOLET = BLUE and YELLOW = ORANGE?

Wiring diagram Problem - Maytag MMV5207A 1100 Watts Microwave Oven


If it is the magnetron cooling fan, it should be a one-speed type.

Assuming your AC line power is correct (110-125VAC) then the fan may be bad, or there may be a problem with the relay on the control board or indeed a bad connection in the wiring.

The way I would test it is to disconnect the fan and the connect a line cord directly to it.

I've uploaded the wiring diagram to my site at:

If you think it's the control board, we repair these for $39.95 in most cases.
