    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.

Need help with my advent 7082 laptop. hot and turning not new still not comeing on

WARNING: Before you start troubleshooting remember that you are dealing with electricity that can KILL. - rules Only work inside the computer case when the power has been switched off and disconnected. Never open the power source. Some of the below steps recommend removing physical parts within the computer. While in the computer it is highly recommend that you be aware of ESD and its potential hazards Laptop fans are designed to keep the system cool by removing heat from the hard drive, processor and other internal hardware components. The fan draws cool air in, then blows hot air out through vents in the laptop case. A faulty laptop fan can cause permanent damage to occur very quickly. If a laptop fan starts making loud noises or stops blowing hot air through the vents, replace it as soon as possible.

Turn the laptop off and unplug it. Unplug or disconnect any external drives or other devices. Move the main battery latch to the "Unlock" position and remove the battery pack. Push in on the optical drive release mechanism, then pull the CD/DVD drive out of the case. Remove the screw(s) that hold the hard drive sled in place, then pull the entire hard-drive assembly out of the case slot. Turn the laptop over. Remove the screws on the bottom that hold the keyboard assembly in place. Flip the laptop over then open it. Lift the front of the keyboard up about 1 to 2 inches. Unplug the flexible ribbon cable that connects the keyboard to the motherboard, then pull the keyboard assembly away from the bezel. Lay the keyboard aside. Unplug the laptop fan. Remove the screws that hold the heat sink/fan assembly in place, then remove the fan from the laptop. Check you CPU central processing unit make sure its securely seated and has thermal paste it might be getting to hot the thermal paste will help disperse the heat Thermal compound is a sticky paste that is placed directly onto the CPU. Allowing for a more direct heat transfer between the CPU and HEAT SINK and preventing air gaps from forming between the CPU and heat sink.

dryer duct blockage caused thermal limiters to trip. four t 20 screws remove the heater bank cover on the back of the dryer. unplug the dryer. unplug the dryer. did i forget to mention, unplug the dryer? remove the heater bank cover, and press the three red buttons in the center of each thermal limiter. at least one of them should click when you press it. replace the cover, plug the dryer in. it will now heat, but if you dont fix the blockage it will trip again.

Checked out Samsung website, E3 error fixed by simply unplugging the unit for 30 seconds. If come back again... then is possible that it has a thermal sensor, this could probably just the problem.

Temp light flashes tried unplugging it for a few minutes turned it on tries to power up but then power , lamp , temp lights flash for a few seconds then it shuts down and temp light stays on

It sounds like you have a thermal issue. The TV is getting too hot or the Thermal Fuse is bad. The thermal fuse detects the temperature in the TV and tells the TV to shut down if it thinks it is too hot. Most likely caused by poor ventilation or clogged fans from household dust. Try moving TV away from wall or cabinet first, if this does not fix the problem, clean ALL the fans in the TV. If problem still persists, replace the thermal fuse.

Just installed an electric cooktop and the Hot Surface indicator light has been on since installation. How do we fix this?

Sounds like a thermal switch which controls the hot surface light is stuck closed.

If this is a new unit, I'd return it. If not, I would check the switche(s) for the hot surface light -- when the unit is cold, unplug one wire going to the thermal switch and check it for electrical continuity. If you get current from a multi-meter through the switch, replace it -- it's not opening when it cools down.

Haier hsp03wna not working

The click you heard is the thermal overload. This snaps open when the compressor is too hot.
Unplug the unit for 24 hours and don't move it.
Then plug it in and see if it comes back on temp.

Gas dryer wont get hot

The first thing to check is the thermal fuse. It is located in the back of the dryer, and you need to remove the back panel to get to it, which involves taking out about a dozen screws. To check it, unplug the dryer, pull the wires off the thermal fuse, connect them to each other with an alligator clip lead, plug the dryer in and see if the dryer gets hot.

With the unit unplugged, check the elements to see if one has become unseated. A gentle push should seat them. Some elements are plug in & can come unseated.
