What is the voltage going in and coming out ofthe Thermal fuse on a dishwasher?

I have listed COMMON problems / reasons why a dishwasher won't start..
The thermal fuse might have blown. The thermal fuse helps to prevent damage to the dishwasher by turning off power so that it doesn't overheat. Once blown, the thermal fuse will have to be replaced for the dishwasher to work. The thermal fuse is usually located in the control panel on the control board or mounted to the bottom of the tank behind the lower panel. The thermal fuse can be checked for continuity.
The door switch, or switches, are sometimes called interlock switches. The door switch prevents the dishwasher from running while the door is open. If the dishwasher won't start, the switch or switches might be defective. To access the door switches, remove the control panel or inside door panel - depending on the model. They can be tested for continuity.
If the dishwasher does not start, the door latch assembly might be defective. These are normally made of plastic and cannot be repaired. If the door won't latch and the door latch is broken, replace it.
The main control board provides power to nearly every component of the dishwasher. If the dishwasher won't start the main control board might be defective. You should first check for more common parts. Many times control boards are replaced unnecessarily because the problem was not diagnosed properly.

If you had a fault in your neutral wire the voltage may have raised to near 220 volts and fried the circuitboard. Replave the circuitboard or replace the thermistor on it. Double check the voltage and the connections where it is wired under the dishwasher.

Check the heat circuit of your dishwasher. This will include your control, heat element, thermostat/thermal fuse, & sometimes your door switch. Check your thermostat/thermal fuse and heat element for continuity first. If all test good, go to your control and possibly your door switch. Check for voltage from your control and continuity of your door switch.Use the VOM. God bless you

If you have no power to your machine and the power is on it is the thermal fuse. If the fuse is blown you will get no power at all. To my understanding after talking to many people the thermal fuse is likely the first thing to go bad on a whirlpool dishwasher. A power surge to your unit would cause the fuse to blow or the control board to go bad.

I had this and the thermal fuse needed to be replaced ($14 part).

If the lights won't come on on the controller and you are sure you have power to the dishwasher, then check the thermal fuse.
1. turn off the power to the machine
2. open the door and unscrew all the screws along the inner edge
3. gently split apart the layers of the door and access the controller; it is inside the door and just below the buttons that are supposed to light up.
4. the thermal fuse is white and clipped onto the side of the control box close to the top of the door.
5. unplug the leads going into it and check it with a multimeter - if no current goes through it then it needs to be replaced

relatively easy fix - good luck!

Open your console and check the continuity of the thermal fuse (clipped to the electronic control unit [ECU]).
Post your model number if you're still having problems and I'll try to assist you further.
Good luck!

will not start

The dishwasher should have a thermal fuse mounted to the control board behind the operator console. It is a small silver colored device attached to a white plactic bracket. In some model dishwashers the wrong gage wiring was used causing the wires to heat up and trip the thermal fuse. There was no apparent risk of fire or anything like that, but the thermal fuses didn't tolerate the heat differential too well. A fix for the problem was to purchase a thermal fuse replacement kit (found at most appliance repair stores) that had thicker wires. The part number for the thermal fuse kit is 959376 and the price is $16.85. You can find it at repairclinic.com. Order on line and have the part shipped directly to you. Now...to access the control board perform the following:

1. Turn off the main breaker to the dishwasher. This is important. Even though the dishwasher is not running, the control board still has live voltages present.
2. Open dishwasher door and remove the top screws that hold the console in place. You shouldn't have to remove the lower screws unless you plan on removing the entire door panel.
3. The control panel should pull off from the front enough to where you can access the control board. There is a thermal fuse mounted on the board with two wire leads going to it. The fuse is silver in color and mounted to a plastic bracket which is mounted to the control board.
4. Cut the wires on the old fuse and splice the new fuse kit to it. Leave plenty of wire to accommodate. There will be instructions included with your replacement kit. Ensure you follow the direction thoroughly and tighten the wire lug screws securely.

NOTE: Do not attempt to reuse the existing wires by simply unplugging the old fuse and replacing it with the new one (been there). The fuse will eventually blow again. Follow the instructions provided and you can't go wrong.

If you have any further quesitons, or if you run into trouble during your repairs, let me know. Good luck to you.

PS If you do not wish to order on line, take the part number I provided you to any major appliance repair shop and they SHOULD have the part available. This is a known problem and a common fail item.
