    Same problem. Repairman came, found a piece of gasket material obstructing the thermistor, cleaned it out, and dishwasher ran 2 cycles and gave the same error message. Called for service again, this time we are told the thermistor needs to be replaced, and it will take 2 weeks to obtain the new part from LG warehouse in California. 2 weeks more will add up to a month of handwashing dishes (from the first upsidedown F and E error message). Repair guy also said he sees "a lot" of thermistor failures on this model. One would expect parts availability if this is a common problem. We have an LG refrigerator that is absolutely brilliant. This dishwasher has not performed well from day one and is obviously a poorer execution than the fridge. I am advising all who will listen to avoid the LG dishwashers.

Thermistor problems are really very rare.  One thing to look for is a possible broken wire in the door assembly.  Remove the front door panel.  Locate the wire harness.  About 1/3 of the way up from the bottom of the door, look for a broken wire.  If no broken wire, look for a kinked wire that may be on the way to being broken.  Once all the broken wires are repaired, the unit should work fine.  If there is no broken wire, then have the thermistor replaced.

see the following steps , use the VOM and fix it. God bless you

  1. Check the power diodeThis electronic component is responsible for transmitting current in one direction. If the diode becomes defective it will cause your microwave to not heat. Test the diode and replace it if necessary.
  2. High voltage capacitorResponsible for storing electricity, this part is a key component in any microwave. Remove, discharge, and test the capacitor to determine if it requires replacement.
  3. Damaged magnetronResponsible for generating waves and producing heat. When your microwave is no longer heating properly, replacement will be required.
  4. Thermal CutoffsExamine the thermal cutoffs on both the magnetron and the oven itself. Take off one of the leads and using a volt-ohm meter on RX1, check the terminals. If you get a result other than zero, replace the thermal cutoffs.

It gives a code sc 542


The error code is related to the fuser area.

Likely to be a low fuser temp issue.


Need to verify good or bad heat lamps.

1) Check each lamp in fuser.

(lamp is good if you get continuity)
(lamp is bad if open)

2) Check the thermostat. (thermal control device)
(triggers if unit gets too hot)

3) Also check thermistor (monitors temp of fuser)
(2) total (middle and rear)

If heat lamp is good:

Your best bet is to change all three items. (Temp fix)

Fuser thermostat - thermal control device
Fuser thermistor (middle front) - thermal control device
Fuser thermistor (rear) - thermal control device

These items wear out. Change at the same time.

Fuser needs to be rebuilt or replaced.

Whirlpool Duet Washer error code A10


Motor Control Unit (MCU)
Heat Sink Thermal Trip
If the thermal protector on the MCU heat sink gets too hot, it will open
the thermal protector on the heat sink which will stop motor functions
and an “F/10” will be displayed.
1. Check for proper installation, verify the unit is not located
near a source of heat and has proper ventilation.
2. Unplug washer or disconnect power.
3. Check wire harness connections to the MCU, the motor,
and Central Control Unit (CCU).
4. Check the drive system for any worn or failed components.
5. Plug in washer or reconnect power.
6. Check the MCU by looking for operations of the drive motor.
7. Check the drive motor for powered rotations.

Error Code "H" and "4"


The meaning of the H4 code is a fuser warm up failure. This means that the fuser is not coming up to temperature as it should within a certain amount of time. This code comes up occaisionally on the AL series for some reason. The fuser unit in cose you don't know is the part that gets hot and is located right where the paper exits the machine. If the code does NOT reset then the part most common to fail is either the thermal fuse or the heater lamp itself.
It all depends on how often the code comes up. Make sure that the machine is not to "cold" at start up. Install a power filter between to the copier and the power outlet to make sure your not getting any line noise that could cause the flase errors. That is about it.

Green light on but no sound from subwoofers or speakers


HI...IT COULD BE A BAD THERMAL FUSE NEAR THE OUTPUTS ....OR A COMPONENT HEATING UP TRIPPING THE THERMAL FUSE TO SHUT DOWN... OPEN IT UP SEE IF THE OUTPUTS ARE GETTING REALLY HOT.. IF IT IS NOT GETTING REALLY HOT... USE A JUMPER WIRE TO JUMP OUT THE THERMAL FUSE IF IT COMES RIGHT BACK ON.. GET A NEW THERMAL FUSE DON'T KEEP THE JUMPER ON (USE FOR TEST ONLY) GOOD LUCK

Inexpensive repair for the temp fix.

The whole Fuser cost can brake the bank.
