Control panel went blank and nothing worked other than pressing a key I would hear two beeps. Replaced the control board and I now have a display but noticed the oven doesnt heat. I checked #4451354 and seems to have continuity. Any thoughts?

Kelkar for Model Number RBD275PBD14

Answer Kelkar, You will want to check with the unit in bake mode for power on the control board between L1 and bake. There should be 240 vac and if there is not then there is a problem on the control board. If there is power then you will want to check for voltage to the element which should also having 240 vac. If there is power then you will need to replace element. If not then you will need to check for burnt or broken wiring from control board to the element.

I have a control board that starting showing an error on screen. I replaced the control board, however, the clock runs 11 seconds fast. I sent the board back for a replacement and when the new board arrived it exhibits the same problem. If I run the countdown timer you can tell it's clicking too fast. A 1 minute countdown takes 48 seconds. I can't believe both control board would arrive defective with the same problem. Someone told me it was the control board transformer. I tested (ohm) the winding and one was good the other seemed a little lower than spec. I have replaced the transformer and still .... clock runs fast. Please tell me the control board received it's clock timing from the 60hz AC line and a bad filter board is most likely the culprit for the incorrect timing. Rich

Rich V for Model Number RBD305PDT12

Answer Hello Rich, The suppressor and line filter would not cause the board to be 11 seconds fast. This would be either in the time circuit or in the home wiring. If the hertz coming into the unit is not correct then this could cause a faster or slower time count. If the wiring is correct then it is in the timer circuit on the control board.

I ran the self-cleaning and then the fan would not shut off. (The oven did heat up, just the fan would not shut off.) We replaced the thermal fuse and it didn't help. Had a tech come out and he said the board was bad. Found a guy on Craigslist who said he could solder and fix the board. After he left, both the lower and upper oven would not heat and the fan ran continuously. Sent the board in to fixyourboard.com and installed it. Now the fan is fixed because it only comes on when the oven is trying to heat but, still none of the elements heat in any mode. The supressor is not in the oven because I was told that I could test it without it. Any ideas on all this?

Robin for Model Number Whirlpool double wall oven

Answer Hello Robin, Yes the unit can be tested without the suppressor on it. You may want to check the thermal fuses to ensure that they are not bad. You would check them for continuity. If they are bad you would need to replace them. If they are not bad then you would need to replaced the control board. You can test this with a multi-meter TJMA-DMT3. Here is a link on how to use a multi-meter. http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html

Ran self clean on oven. Now have nothing on display and door locked. Replaced thermal overload and no difference. Then saw V1 on the suppressor was fried. Replaced that and still no display. There is power going into and out of suppressor. There is power going into circuit board, but no power coming out of board. Would a bad door latch motor, circuit board, transformer cause this?

Both controls on my oven don't work. They flicker so that the time and temperature are reset every few seconds. Could that be caused by the suppressor, which appears to be the only common electrical component for the two sides?

Ken C. for Model Number kitchenaid KDRP487MSS

Answer Hi Ken. I would use the digital capacitor Tester / Volt/ohm meter part # TJMA-DM1. At the terminal block, make sure that there is 240 vac between both outer legs and 120 vac from neutral (middle) terminal and each outer leg. Use double nuts on each terminal stud to keep the terminal wires tight. Look at the suppressor red (or blue) round flat varistors to see if they are cracked or if the board is cracked. Part # 4451985. You have an internal supplied wiring diagram inside the top. Thank You.

There is a humming sound coming from the vicinity of the control panel of my oven. Do you think the control panel needs to be replaced or is the suppressor bad? The control panel works fine although the clock led is on it's way out.

Jrodela for Model Number kebs208dss8

Answer Hello Jrodela. Based on the information you provided, it sounds like the control board 4453661 may be bad on the unit. Remove the control panel from the unit and see if that is where the noise is coming from. If so, you will need to replace the control board. Hope this helps.
