For Whirlpool Microcomputer (Part Number: OEM9533805)

Fran Sutherland for Model Number RBS245PDB12

I have a Whirlpool, "built-in" , 24 " electric oven, Model: RBS245PDB12. The upper broiler element never shuts off. If I set the oven to a 350 degrees on "Bake", the element continues to heat and never shuts off. If I press the "off" button, the oven continues to heat, will not shut off and I must flip the fuse off. The door latches and locks when this happens and will not open for about 1 hour until the oven cools. I changed the sensor but this did not resolve the problem. Please help. What do I need to purchase? Thank you. Fran Sutherland

Fran, The "Broil" relay on the [AP3177932 8186024 Microcomputer (control board) has stuck closed and is supplying constant voltage to the Broil element. You will need to replace the control board. Unfortunately, the part is presently out of stock, and will need to be ordered from the manufacturer. This will add a few days to the delivery time, once you place the order. Thanks,

Dale, For a proper diagnosis, we would need you to please verify the model number from the units' I.D. tag since it will not come up for us as a valid model number.

Justin, You would want to check the resistance of the oven sensor for a resistance of 1090 ohms at room temp. If the resistance checks ok then the control board would be the issue with this unit.

Jay, The F3 E0 is an open temperature sensor. You will want to check the wiring between the temp sensor and the control board to make sure that it is not damaged. If this checks ok then do a resistance check on the oven sensor. The resistance should read 1080 ohms at 70 degrees and if you test it during a cycle you would add 2 ohms for every 1 degree of temperature rise. If the resistance is not correct then replace the oven sensor. If the resistance is good then this would be a faulty control board.

Hello Bob. That is a door latch error. 1. Check the latch assembly: latch arm pivot joint, arm/solenoid connection, solenoid spring, and spring washer. 2. Check the Latch Solenoid: - Check for firm electrical connections. - Disconnect the two wires from the solenoid and measure the resistance of the solenoid. A small resistance (approx. 175?) is normal. If the solenoid is open (8?) or shorted (0?), it should be replaced. 3. Check the Latch Switch. Disconnect it and use a continuity tester: - Door latched = switch closed, continuity should read 0?. - Door unlatched = switch open, continuity should read 8?. 4. Check Door Open/Closed Switch. Disconnect it and use a continuity tester: - Door open = switch closed, continuity should read 0?. - Door closed = switch open, continuity should read 8?. 5. Check power and element connections.
