How to service a temperature switch

This control panel switch regulates the temperature of the water in the tub. It also plays a role in controlling the fill cycle. If you suspect this switch is faulty, remove it and hook a test wire across the switch terminals. If water flows, the switch is faulty. If the switch is faulty, replace it with a new one of the same type. Connect the new switch the same way the old one was connected.

If there's a problem with both water temperature and tub filling cycles, both the temperature switch and the timer may be faulty. Test both components and replace them as necessary. Procedures for testing the timer can be found below.

top loader washer won't fill with water


Either the water level sensor is faulty or the selector switch is bad.



Servicing the Water Level Control Switch

This is another control panel switch, usually located next to the temperature switch. There is a small hose connected to this switch, and sometimes this hose becomes loose and falls off the connection. When this happens, the water in the tub usually overflows. To solve this problem, cut about 1/2 inch off the end of the hose and use a push fit to reconnect it to the switch.

The switch itself can also malfunction, resulting in tub overflow and other water-level trouble in the tub. If you suspect this switch is faulty, remove it by backing out the screws holding it in place. Take it to a professional service person for testing. If the switch is faulty, replace it with a new one of the same size and type. Connect the new switch the same way the old one was connected.

washing machine stops half way through the cycle


When the cycle doesn't advance, it's probably the timer or a cold-water supply problem:

  • It's the timer, if your washing machine fills with water and begins agitating, but the timer never advances--or if the washer is in a spin cycle and the timer won't advance. Then you need to replace the timer.


  • It may be a cold-water supply problem, if the washing machine fills with water, agitates, drains, and spins, but then doesn't fill with rinse water. See There's no cold water.

Kenmore 80 series overflow


The water level switch senses the water level in the wash tub. It does this through a plastic tube which runs from the switch in the control console down to the side of the outer tub, near the bottom . The tube is filled with air. As water enters the tub it also enters the tube. As water climbs inside the tube, it pushes on the air trapped inside and increases the air pressure. When the air pressure reaches a certain level, it triggers the switch. Inspect the air tube for kinks, breaks or damage. The tube should also be free of water. The tubing should be securely connected to the bottom of the outer tub and to the bottom of the water level switch. If the Tube is full of any water, remove it from the switch and replace it with a new one. Make sure that the new is correctly fitted to the switch.

The switch routes current from the timer control to the temperature switch and the water inlet valve when the tub needs to be filled. Once full, the pressure switch cuts the current and reroutes it to the motor on the timer control to continue the cycle. If the tube replacement dose not improve the fill performance, and it continues to overfill, replace the timer.

Candy Nova CN126T - No hot water


hi This control panel switch regulates the temperature of the water in the tub. It also plays a role in controlling the fill cycle. If you suspect this switch is faulty, remove it and take it to a professional service person for testing (the test takes special equipment). Or, hook a test wire across the switch terminals; if water flows, the switch is faulty. If the switch is faulty, replace it with a new one of the same type. Connect the new switch the same way the old one was connected.
If there's a problem with both water temperature and tub filling cycles, both the temperature switch and the timer may be faulty. Test both components and replace them as necessary. Procedures for testing the timer can be found below.

washer continues to work even if water is not filled to top and even if i try to stop continues to spin


A defective pressure switch can interfere with the cycles that depend upon the switch to indicate when water has filled or emptied from the tub. It can also result in underfilling or overfilling of the tub. The switch routes current from the timer control to the temperature switch and the water inlet valve when the tub needs to be filled. Once full, the pressure switch cuts the current and reroutes it to the motor on the timer control to continue the cycle.
