Customer Questions and Answers for High Limit Thermostat Kit by Whirlpool

Douglas, You will want to test the hi limit to make sure that it has continuity. It would also be recommended to test the gas coils to make sure that they are good and check the operating thermostat to make sure that it is not defective.

Dave, You will want to check the venting of the unit to make sure that the venting is clear. If this is ok then the most likely cause would be weak gas coils on the unit.

Jimmy, With the unit not shutting off by itself then this would be more likely a timer issue. It could be a cycling thermostat if the timer is not advancing and you could check the thermostat for continuity to make sure that it is good.

Andrew, You described the classic gas valve coil failure. After a few cycles the magnetic coil will "breakdown" and will not raise the internal plunger to allow the gas to flow through the valve body. Replace the gas valve coil kit 279834 / 694540 and you should be fine. By the way, all the thermostats should have a "closed" circuit at room temperature. The coil kit is in stock and available at this time. Thanks,

Andrew, It would be possible that the cycling thermostat would be the cause of the unit no igniting but would be more likely the gas valve since the igniter is igniting.

Hello Ed. You will need to check and see if the cycling thermostat is bad and will need to be replaced on the unit.

Patrick, Check the broken belt switch to make sure that it is good and is depressed. If this checks ok then the motor would be the issue with the unit not starting.

Hello Ray. You will need to check the cycling thermostat and all the wiring on the unit. Also, make sure your house breaker is good.

Hello Tom. You will need to order W11050897 for the thermostat.

Hello Felix. It does not matter which wire goes where.
