Customer Questions and Answers for High Limit Thermostat by Whirlpool

George, Since the igniter is coming on and glowing and then goes off, the coils have been replaced, this would mean the thermostats are working and the issue will be a gas valve that is faulty. The part number for the valve is W10116794 but unfortunately, has been discontinued by the manufacturer with no suitable replacement.

Greg, Based on this information it sounds like the issue will be caused by a faulty gas valve on the unit but will want to check the gas pressure that is coming into the unit is 10 Water column inches of pressure.

Hello Bill. Try replacing the igniter. If it continues, replace the gas valve on the unit.

Hello Henry. Make sure the vent is clear and venting good. If so, you can test the exhaust temp. As long as it doesn't go over 165°, you should be fine. You can test this with a multi-meter TJMA-DMT3. Here is a link on how to use a multi-meter. http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html

Hello Todd. Check the coils and see if they test good. You can test the coils using a multi-meter MA-DM1. The two prong coil will read 1,000-1,300 ohms, and the three prong coil will read 1,300-1,400 ohms across prongs 1&2, and 500-600 ohms across prongs 1&3. Test the coils after running the dryer for about 10 minutes.

Ed, It would be the coil assembly 279834 that's at fault. If the flame sensor WP338906 was the issue, the igniter would not glow, or would not cycle off, and the burner would not ignite.

Jay, Your description indicates the tub sensor 304997 and spark gap 306130 are not sensing/feeling the wet clothes. The control board "thinks" the clothes are dry and then the control steps into the five(5) minute cool down cycle and shuts off. The sensor is located in side the drum just below the lint filter grille on the front bulkhead. To replace the spark gap, you will need to remove the two(2) Phillips head screws at the top of the dryer front panel, lean the panel out at the top, so access the 1/4 in. hex head screw that holds the spark gap to the front tumbler support assembly.

Sonny, Based on the information, and apparently you have a digital multi meter, your readings are pretty much in range, except the hi limit switch WP303395 it should also have a reading of 000 "closed" circuit at room temperature and an "open"(infinite resistance) circuit when the temperature reaches 220 dgrs.F. When testing the gas valve coils, you need to let the dryer run and heat for a few minutes (10 - 15 minutes) then test the resistances. You quite often get a false reading, when the coils are "cold".

Ruly@membrila.com, The x does not have a significance on which way the wires are attached as this is not a directional thermostat yet it is a bidirectional.

Hello, The only thing that can cause the issue is either the neutral is being dropped through the centrifugal switch in the motor, or the gas valve has a mechanical issue.
