SOURCE: Thermal fuse keeps blowing

Mr. Larry (guru?)
The thermal fuse is just that It doesn't protect the circuit from over current although it certainly can open in that case. It is there to protect the board from overheating , thus the term thermal. The dishwasher could be allowing the water to heat too hot or the water heater in the home is turned up too much. The heater could also be shorted to case thus allowing it to be on even though the control is not calling for it especially if the polarity is incorrect to the dishwasher or the relay on the board could be welded closed so that the heater can't turn off even though the thermostat is satisfied. The best thing is to get a person who can check these things. You don't necessarily need to change the board with a fuse. I have changed many fuses with no other problems and verified that the machine was still working years later. sometimes the fuse just blows!

If there are no lights on the control panel then initially check if connections to the panel are fine.If they look fine then you definitely need a new control panel. No need for a new touch panel.Its always that the control panel goes faulty,not the touch panel.
you can also check for competitive rates from local dealers and few sites like--repairclinic.com and applianceparts.com
thanks.

SOURCE: MDBH945AWW maytag dishwasher panel lights will not

These control boards do not have fuses on them. I opened mine up when the front panel touch pad stopped working and the LED indicators were anemic. This is a sign of the ribbon cable connections have oxidized. The ribbon cable connects the touch pad to the control board.
Others have written up nice solutions on similar Maytag diswashers with the touch pad.
http://www.fixya.com/support/t387192-maytag_quiet_series_300_no_power_touch

The previous expert shows that you can diagnose this by using a 10k resistor and connecting pin 6 and 10 on the ribbon cable connector and it will start the dishwasher (you have to trip the door handle and carefully do this with the power on). This proves that the control board is fine and ribbon cable connections are the problem. Don't forget to quickly trip the door latch once the dishwasher starts.

My solution was to purchase a contact cleaner called Deoxit. You can order from RadioShack.com or get at Frys. Spray Deoxit on both the ribbon cable end (removed) and into the connector on the control board. Deoxit removed the oxide on the connectors. The twin pack Deoxit spray comes with a solution that helps prevent corrosion. I am 1 day into the successful repair of this model Maytag dishwasher.

Previous people have suggested heat and steam get into the control board and oxidize this connector. I notice on the top right where the control board sits, there is a gap to allow steam to get into the door/control board area. I used bathroom caulk to seal both sides of the door to hopefully prevent further corrosion.

Timer light on front panel of dishwasher has stopped working--how is it replaced?


Most of the led lights are fused to the circuit board. Sounds like the circuit board is going or gone bad. I'm not sure because you did not give the model of the dishwasher.

Most of the control lights are led and do not go bad. But the circuit board that controls the lights can go bad. You may be able to fix the control circuit board but replacing it would be easier.

Where is the fusible link for my LG dishwasher?


If the 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.

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.

Maytag dishwasher model MDB7100AWB has power to dishwasher but nothing works (as if there was no power). Is there a fuse in the dishwasher somewhere? If not, what is the most likely cuase? Thanks.


Hello,

No thier is no fuse so what the most likely problem will be a defectice door switch switch so even though the door is closed the switch thinks its open and will not allow the dishwasher to start.

Whirlpool GU2500XTP dishwasher went dead in mid-cycle.


"Wondering if this model has had reliability issues with the circuit card." ...If by circuit card you mean the electronic control board, that part number is used in many other models as well. In my experience with these control boards, I believe they have a low failure rate.

Make these checks if you haven't done so yet...
Check for 120V (breaker). Look for loose/shorted wiring connection at the dishwasher's junction box. Check all wiring connections to the control panel, electronic control and thermal fuse. Test the continuity of the thermal fuse (part # 8193762). If that's ok, you have already replaced the control panel so the problem is likely with the electronic control board (part # 8564546).
Good luck.
