Switch Postions SHU43C02

Can anybody give me the positions of the switches when they are operating (ie: Normally open, normally closed, etc.) and off. I am particulary interested in the tow switches in the water level switch and the flood switch.

Thanks.

You need to use a tester and check for yourself for whatever you are looking for.

Need schematic for motor switch 3952056


It's a centrifugal switch. if there are 4 contacts then it is like 2 switches that are normally open. No schematic is necessary. You can easily take apart, clean, re-bend etc many centrifugal switches... or just replace them with a new one.

Nothing is turning on it worked last time i used it


My guess if you already made sure it was plugged in and the outlet is good, I would say the door switch is bad. You can check it with the power supply disconnect by using an ohm meter it should give resistance and say ol when open and closed. The service manual is normally behind the door panel if you remove it.

My dishwasher has power to it but the heat dry option is lit and it wont start ant idea what to do?


Hello

Do you have any of the extra functions selected, such as "Hi Temp Rinse" etc?
The selector switch has a selection for Hi-Temp Wash; the switch is in parallel with a thermostat mounted on the bottom of the tub and with a contact in the timer. The
selector switch, temp assure thermostat, and the temp boost thermostat are all in series with the timer motor. Both thermostats are normally open thermostats. When
the timer reaches the end of the second wash cycle, the contact in the timer supplying power to run the timer motor will open. At which time, if the selector switch for the Hi-Temp Wash has been selected, power to run the timer motor must come through the thermostats. The temperature of the water in the tub must rise to 137° ±5° F for the thermostat to close and the timer motor to advance. If the water temperature is below 137° ± 5° F, the timer will pause until the heating element raises the temperature of the water in the tub and allow the thermostat to close.

Hi-Temp Rinse
If the selector switch was a selection for a Hi-Temp rinse, the switch is in parallel with a thermostat mounted in the tub, and the contact in the timer, the same as the Hi-Temp wash. The operation for the Hi-Temp rinse will be the same as for the Hi-Temp wash with the exception, on some models, the temperature of the water in the tub will be 150° ± 5° F for the thermostat to close to give a sanitizing rinse.


What do we learn from this? That you either have a bad heater or a bad thermostat. Check the heater for continuity with our OHM meter.

Dishwasher won't run. Normal light and cancel light flashing cont


Hi,


The door latch pulls the door tightly closed to prevent water leakage around the door. It is also designed to prevent operation while the door is open. The door latch works in concert with the door switch to ensure that the door is tightly closed and latched.The door switch is a separate part from the door latch and is found inside the cabinet. The switch is off when the door is open. Depressing the switch closes the circuit and enables dishwasher operation. Closing the door does not depress the switch all the way. Only when the door is closed and latched, does the door fully depress the switch.

If the door latch is not properly aligned it may not pull the door tightly closed and the door switch will not be fully depressed. Unless the switch is fully depressed the dishwasher will not operate. It is a simple matter to determine whether the door latch is the problem. Simply open the door, close the latch and select a cycle and depress the switch. Note that if the test is successful, with the door open, the dishwasher will operate and water may spray out. Make sure to first remove all tools from inside the dishwasher. Do not reach inside the dishwasher during the test. Now, inspect the cabinet where the door makes contact with it and locate the door switch. It may have a protruding button or spike or more likely it is a hole with a piece of metal or plastic inside it. You must fully depress that switch. If the switch is recessed, then use a non-conductive object, such as a wooden pencil, to depress the switch.

Thank you !!

When I close the door to the microwave, the timer is working but the microwave isn't. I believe the door latch is no longer engaging a contact point to make it work. Like the door was still open. Model #JE...


there are three switches in the door latch inside. One of them is not making contact. Remove the cover, find those switches and check for continuity with door open and door closed. If there is no continuity on one of them with neither of the door positions - rpelace that switch. GE part are expensive for no good reason, so replace with a different brand switch, with at least 15Amp rating, ie 28QBP0495

Siemens SE25M851 randomly looses power. power to the unit is fine ie fuses ok and constant power. if i give the unit a bit of a jiggle it some times comes back to life. any suggestions?


It could be the lid switch. See if "jiggling" the door handle pin points the problem. The door switch normally sits behind the door handle.

If so, it is either a faulty door switch, or more likely a brocken piece of plastic which holds or triggers the lid switch.

Good luck.

No power to the main water valve during cycle.


I'm no expert, but I recently had a fill valve replaced. There is a float switch at the bottom of most dishwashers. Its purpose is to cut power to the normally-closed electrically-opened fill valve in the event of an overfill. If the float switch "thinks" there is an over-fill situation, it will cut power to valve, closing it. I would start with replacing the float switch or checking to ensure that it is not stuck in the "up" position due to debris.

Again, I'm no expert.
