Question about Washing Machines

2 Answers

Gas dryer not maintaining heat. The dryer heats at the start (after rest), and maintains the heat for about 15 minutes. After that, the dryer continues to tumble, but the dial (i.e. control timer knob) never moves if Auto Dry is chosen (the knob does move in Timed Dry.) I did remove the front panel plug & can see the heating elements glowing intermittently. The light cycles on & off once (not sure if that's right?) I don't know where the fuse is(even with the repair parts list I can't make it out), but if it heating at all, does that mean the fuse is OK? 70 Series Kenmore/Whirlpool 76722695

    As I told you the fuse is not the problem.
    Not sure how this problem got posted twice, but thanks for two answers. Fuse is good, got it.


    I forgot to tell you to check the lint filter first, if the lint filter is dirty, you can get reduced heating and the dryer can behave erratically.

    The lint screen is clear. I did follow the Troubleshooting instructions in the Owner's manual for "Not Drying Satisfactorily":


    • Exhaust vent is no crushed or kinked; I removed & vacuumed it out, and it exhausts to the outside of the home when connected.

    • Reset the circuit breaker.

    • Gas valve is open, and line is connected securely (we still have hot water in the house, so I think the gas is good, but possibly restricted?)

    • Timer is not set to "Air Dry"

    • Dryer is level

    • Nothing blocking the outlet grill

    • Clothes are not overly wet.

    • Load is not too large.

    The problem persists. Maybe there is lint below the filter?

    The problem is either the dampness sensor, or the board controlling the sensor.
    The sensor (or the controller board) open or closes (depending on model) the circuit too early, and the dryer stop heating.

    Is it telling that the light/glow is continuous at the beginning, and then starts to cycle on & off after about 15 minutes? Or is that normal?


    Any recommendations for online part ordering?

    Always keep your appliance unplugged if you DIY.

    Got it.

SOURCE: Gas dryer not maintaining heat.

The problem is with the 2 little circular black coils next to the ignitor. They need to energize before the gas valve can open. They tend to get weak over time. I am 100% sure this is your problem. Good luck :)

Runs but does not heat up, I removed the bottom from cover under the door and saw that when I turned it on the machine starts running, the thing that ignites the gas heats up to a bright redishish yellow...


Hi,

If you are having problems with your gas dryer not heating the most common problem is that the ignitor goes bad. Even though it glows sometimes it is still not working properly.


if you dryer is gas check out this gas no heat tip....


If you have an electric dryer, you can have many different things that can go wrong causing the dryer not to heat.


check out this electric no heat tip...

Gas Dryer. Heat for only one burn cycle.


Try vacuuming out the intake and exhaust of the burner to remove any lint or other debris. If no help, the main burner may need to be replaced.

Gas dryer not maintaining heat. 70 Series Kenmore/Whirlpool 76722


Fuse is ok . Problem is the soils on the burner valve . If the dryer heats when started , the electricity goes thru the coils to open the valve . Once the coils get warm , 1 will open (short) until it cools back down . The coils can be replaced just by removing the front panel . Only 2 screws hold the coils in place . No turning off gas , dissasembling dryer .

Kenmore gas dryer starts to heat but does not maintain the heat. It cools down after a few minutes.


Something simple for you to try is: remove the duct from the dryer,run a cycle,IF the unit works fine, you will need to have your vent system cleaned to the outside. If you still have troubles, you will need to place a service call to have the unit diagnosed

Check coils on burner assembly. Often when a dryer heats initially and then stops heating a coils has gone bad.
