Question about Dexter 9857-147-001 - Ir Control Board
Did you try a parts store or wear you bough it is the relay on board or on the motor
Posted on Jul 24, 2013
Testimonial: "the relay is on the board and I have tried everywhere, parts stores, repairs shops that wont sell me parts. to emron themselves. the dryer manufacturer will only sell me a complete board for over 500.00. I did find a complete board for 395.00 still I think I can repair it myself without having to send the board in."
a 6ya expert can help you resolve that issue over the phone in a minute or two.

If the proper voltage is coming into your control board and you are not getting voltage at the MW relay, then you need to replace the control board. If voltage is interupted by a thermostat or switch from your testing to the control board, then replace that part.
Now, testing from the MW relay on to your transformer, high voltage capacitor, magnetron, and diode.Do not do any voltage reading from the secondary side of the transformer on, this can be a deadly microwave oven repair if you do not follow directions. This can result in electrocution and the "blowing-up" of your voltmeter, only do OHM testing with the power off and the capacitor discharged. Someplace in this circuit, usually before the transformer, you will have another thermostat to test. It is usually mounted on the magnetron. Do a quick OHM test to see if it is open or closed.
Now to test either the transformer, high voltage capicitor, magnetron, and diode, you must test each part separately. A good rule of thumb, if your capacitor is bad, change the diode also. Another note, if you are working on an OTR model and you have determined to be one of these "heating" circuit parts, you can not test these parts until you take the unit down. If you don't have the parts with you and you have to order them, order the magnetron, capacitor and diode and you will have a 90% chance of solving the problem. If it is an older microwave, order the thermostat also, most times you can return un-used, un-opened parts. Check with your parts supplier. This way you only have to take the unit down once.
To test these parts, scroll down this page and you will see a chart with component tests. Follow the instructions to find which part(s) are defective in your microwave oven repair.
Microwave Runs, Heats, but turntable does not move This is a fairly easy one. First, make sure the turntable coupler under the glass dish is not broken. Second, on the control board, find the turntable relay and test for voltage. Some turntable motors are 24 volts DC, so make sure your testing the correct voltage. If no voltage from the control board, then replace the control board. Otherwise head towards the turntable motor.
On OTR models, you can get to the motor by un-screwing the bottom panel on the microwave. On countertop models, there will either be a knockout or screw on access panel. Check for voltage at the motor. If no voltage, check the wiring back towards the control. If voltage, then replace the turntable motor. The component list below also shows how to test a turntable motor.
