Have a blank panel board have sent in for repair thought it was out. Have re-installed and still have a blank board. Checked to see if power was going to transformer put meter across both red wires and nothing. At a loss
Answer Steve, you will need to check the control panel thermal fuse 4456654 for a "closed" circuit, and voltage across connector P19 pins 1(black) and pin 3(white) for 120 VAC into the ERC/Clock and out to the transformer (120 VAC across the red wires, and 20 VAC out of the transformer to the control, across the two blue wires).
No lights on the control panel. The oven will come for about 1 minute and then goes off. The transformer has 20+ volts.
If the control panel is going out and the transformer is good then the control board is faulty and would need to be replaced.
My power transformer resistance measurements came up different than those listed on the Tech Sheet. Primary winding P16-5 to P16-7 called for 75 to 95Ohms and my readings were 58. Secondary winding P16-2 to P16-3 called for <1 ohms and my readings were 2.5 Ohms. Does this mean I have a short in the transformer and would this cause the LED lights to stop working?
Answer Dennis, based on your information, the control transformer is not shorted. But it has been under a load and stressed. We prefer to check voltage at the control board, it's a bit more accurate, but you need to be carefull. Check for 120 VAC across p16-5 and P16-7 (red wires on the control board out to the trans former. Then, across P16-2 and P16-3 (blue wires) for 12 to 20 VAC out of the transformer. If you have the voltages the transformer is good, and you'll need the control board. If the voltages are lower or not there, you'll need the transformer.
My clock is very dim. I was thinking perhaps replacing the tranformer? It keeps time and temp. What do you think it could be?
Answer John, very good guess and a good inexpensive place to start. At the control board on connector P16 across pin 2 and pin 3 (blue wires) I'd expect to see 20 VAC +/- 10% if the control transformer is working properly. If so the weak display circuit would be in the control board itself W10438751 . Thanks and Good Luck
I put my oven on self clean and after it finished the top oven door stayed locked and and no power was showing. Husband checked outside breaker and inside connection. What could it be?
Answer Hi Naeomi. You need to remove power. Use a metal hanger to form a hook onto the end of it and reach in from the side. Pull the latch mechanism open. This is caused by a failure of the oven sensor during cleaning. Shorting out the sensor will tell the control there is a possible "safety" issue and to shut down immediately. This may effect the latch motor assy. needing replaced also. This way you can retrieve the model # and get back with us. We in turn will provide the part #'s for your unit. Thank You.
