Troubleshooting an F90 Error Code on a Range

Hi. Wayne here from Sears PartsDirect. In these days were going to speak about what todo whilst you see an F90 error code on your variety. Youll see this code while you attempt to lockor unencumber the oven door on a range with a lock characteristic like this one. The F90 code manner the digital oven controlboard detects a trouble with the door lock approach. The F90 code can show up while you try to starta self-clean cycle, which uses the door lock. You would additionally see the F90 code when the self-cleancycle ends and the digital manipulate cant unlock the oven door. In this troubleshooting video, good examinethe add-ons in the door lock method to find out which section has failed.These incorporate the control board, the wiringand the oven door lock motor meeting. The oven door lock assembly involves the doorlock motor and the door lock swap. Lets get began. You desire a nut driver to remove the rangeback panels and a multimeter to participate in electrical exams during this troubleshooting. You can too desire a Phillips screwdriver todisassemble ingredients for trying out. First, unplug the range and pull it out ofthe cabinet. If you have a gasoline range, shut off the gassupply. Cast off the screws and pull off the highest andthe backside again panels. Examine the wiring connections between the controlboard and the oven door lock meeting. Reconnect any free wires and restore any brokenor broken ones. This easy step could repair your door lock problemand clear the F90 code. If you to find and repair a damaged or disconnectedwire, reassemble the variety and restoration energy to it.You should hear the door lock motor run whenyou plug it in, whilst it finishes locking or unlocking the door. If the wiring connections between the controland the door lock assembly look k, well verify the door lock change next. The door lock change rests towards the camand detects motor movement. If the switch breaks and cant notice cammovement, the range shows the F90 code. To peer if the swap or wiring is damaged,well determine resistance through them. Disconnect the wire harness plug with orangeand grey wires from the manage boardits the orange and gray wires that join tothe door lock change.Well investigate the switch and its wiring withthe switch arm in two one of a kind positions: pushed in and expanded. Together with your multimeter set to measure ohms,contact one meter probe to the orange wire and the opposite meter probe to the grey wire onthe wire harness plug. Now, reverse the role of the switch arm. If the switch arm was once expanded for the firstreading, use a screwdriver to press it in in the course of the 2nd experiment. If it was pushed in for the primary scan, removethe cam screw and pull off the cam to release the switch arm for the 2nd scan. Once youve reversed the function, touchone meter probe to the orange wire and the other meter probe to the grey wire on thewire harness plug. If the multimeter measures close zero ohms withthe arm pushed in and OL with the arm multiplied, the change and its wiring are ok. That you can bypass to the next component of this videoto investigate the door lock motorjust seem for the title slide that says Door Lock MotorTesting.If the multimeter measures the same resistanceregardless of arm position, it signifies that both the switch is damaged or the wiringfailed. To assess whether or not the change or wiringis at fault, disconnect the wires from the change spades. Repeat the resistance experiment with the arm pushedin and with it expanded, by touching the meter probes immediately to the change spades. If the multimeter measures the equal resistancethrough the switch spades regardless of arm position, change the switch. But if the meter measures near zero ohms withthe arm pushed in and OL with the arm improved, substitute the wiring considering you know the switchis okay. If the oven door lock swap and its wiringare okay, assess the oven door lock motor and its wiring via measuring resistance throughthe brown and white motor wires that connect to the manage board.The multimeter will measure about 2,000 ohmsthrough the door lock motor and its wiring if the motor works as it must. If so, youve now ruled out the door lockswitch, the door lock motor and the wiring as motives for the F90 code. By approach of removal, a failed controlboard is causing the F90 code, so substitute the manage board. Watch our video replacing a variety OvenControl Board to learn how. If the meter measures OL or close 0 ohms ofresistance via the door lock motor wires, unplug the brown and white wires from themotor and measure the resistance across the motor spades. If the multimeter doesnt measure about2,000 ohms on this scan, substitute the oven door lock assembly on the grounds that the motor is unhealthy. Watch our video exchanging a Door Lock inan electrical range to learn how.If the multimeter measures around 2,000 ohmsof resistance by way of the door lock motor, the wiring between the motor and the controlboard is damaged. Check resistance between the ends of the brownwire and the ends of the white wire. The multimeter will measure near zero ohms ofresistance if the wires are okay. Repair or substitute a wire if the multimetermeasure OL. Also check the resistance between the controlboard ends of the brown wire and white wire. Make certain the opposite ends of those wiresdont touch each different or something else. The multimeter measures OL if the wires aresound. If it measures 0 ohms or any resistance valueother than OL, damaged wire insulation is enabling the interior wire strands of thebrown wire to touch strands of the white wire. In finding and restore the wire injury. After you restore the wiring or substitute thefailed phase, reassemble the range, plug the power twine again in and slide the range backinto the cupboard.The code must disappear, and the door willfinish locking or unlocking. Unlock the door if it locked and reset theclock. Well, i am hoping this video helped you out.
