Dryer T712W - Sensor not accurate New Dryer. Problem since purchase. Sensor and "mother board" changed by authorized repair company. Sensor till inaccurate. It "cooks" my clothes.

Its probably neither of those, its the timmer, Does it have one of those Turn Dials that you use to set it, or is it all electronic with buttons?

If its the later, then never mind.

On the turn style the timmer breaks and wont shut off and you can still hear the " TIC TIC TIC" even after opening the door.

If its electric display then its probably the temperature sensor. If its new, its under warranty and they need to come out and fix it, or get you a new one at no charge.

Pull the dryer out away from the wall. Unhook the vent from the dryer completely. Do not put anything over the dryer exhaust on the back of the dryer. Do a normal load with the vent unhooked. If it dries better or ok like this then the problem is in the dryer venting. Like a blocked vent pipe or a smashed or restricted vent hose.
- If the vent doesn't make a difference, then check the blower wheel for excessive lint build up, check that there isn't anything stuck to the air intake baffle inside the drum, (i.e. the screen on the back wall of the dryer when looking into the drum). Check the lint filter chute for blockage. Check that the heating element isn't shorted to ground. Check the exhaust temperature of the dryer. A meat orpocket thermometer can be used for this. It should cycle approx between 120 degrees and 160 degrees ( without clothes ). Check that the drum seals are not worn out.
if it over heats
t overheats Usually when an electric dryer overheats it's because of a defective cycling thermostat or a clogged vent system. Clean any lint from the internal and external ductwork, and/or replace the cycling thermostat (read about cycling thermostats in "Drying is too slow," above).

f your clothes get marked or torn in your dryer, check these:

Rollers
Rear seal
Front glides
Front seal
Rollers Your dryer may use rollers, or wheels, to support the rear of the clothes drum. When these are worn out, they may cause the clothes drum to drop down slightly, which can pinch the clothes between the top of the clothes drum and the rear of the dryer interior. When the rollers wear out, you need to replace the whole set.

Rear seal Your dryer may have a felt-like seal at the rear of the drum. If this seal is worn, torn, or missing, clothes can get caught and torn in the space between the clothes drum and the rear of the dryer interior. When the rear seal wears out, you need to replace it.

Front glides Your dryer probably uses nylon or plastic glides at the front of the clothes drum for support. When these are worn out, they may cause the clothes drum to drop down slightly, which can pinch the clothes between the top of the clothes drum and the front of the dryer interior. When the glides wear out, you need to replace them as a set.

Front seal Many dryers have a felt-like seal at the front of the drum. If this seal is worn, torn, or missing, the clothes in the dryer may get caught and torn in the space between the clothes drum and the front of the dryer interior. When the seal wears out, you need to replace it.
if the clothes smell to be burning out If you don't clean out the lint trap frequently, your dryer may have small lint fires inside the cabinet. The smell from these fires can leave a strong odor in the clothes drum.

Also, if there are any solvents, paints, lacquers, etc. in use in the house, your dryer may alter and/or amplify the fumes to an odor unlike the natural fumes given by the solvent, paint, etc.

Here's what to do:

• First, clean all of the lint from the inside cabinet and ductwork of your dryer.



• Have a qualified appliance repair technician inspect the dryer for damage caused by any lint fire.



• Move all containers of flammable liquids at least 50 feet away from the dryer. Gas dryers have a large flame when operating properly and can ignite the fumes of any flammable liquid or gas.



• Then, try to clear the odor, by running a couple of loads of old rags or towels.

The sensor is not that accurate in distributing heat. It needs to be replaced. It might have been cooked as well.

A - Things that could stop a electric dryer from heating:
- house fuse or breaker ( needs two of them ), heating element, burnt wire, thermostat(s), thermal fuse ( not all models ), motor heat switch, timer, selector switch, burnt power cord/plug.
A ohm meter test for these parts is here.
Q - My gas dryer will not heat, what could stop my dryer from heating?
A - Things that could stop a gas dryer from heating:
- glow bar igniter, thermal fuse ( not all models ), coils on the gas valve, gas valve, thermostats,motor heat switch, timer, selector switch, sensor.
