dryer runs normal for several heat cycles then displays cool and shuts down after 5 min. I checked vent and replaced coils and thermoster
Answer 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.
i have done my trouble shooting but i continue to have intermittent heating problems. the burner comes on and off for about 30 seconds each time, the igniter gives a bright amber glow. the readings I took appear to be ok from: thermal switch (001), igniter (049) , burner valves (two prong: 1.2, three prong: 556), flame sensor switch (01) and the high limit thermostat (.04 and 7.1) the gas flow is ok (unobstructed) and the vent duct is clear. your assistance is greatly appreciated. thank you.
Answer 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 303395 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".
replacing part# 303395 on Maytag MDG5500aww ..one of the terminals is mark by an x...does this indicate the purple wire must be attached to this terminal? Thank you
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.
