Q:

Whirlpool dryer model LGR7646AQ2 not heating

A:

A dryer is an appliance we depend on so much, when there's laundry to be done.  I have taken some time to research your question here on the Manage My Life website and I noticed that someone else had asked a similar question with a posted response from an expert. Have a nice day!

I know that it can be very frustrating to have issues with your dryer. There are several things on this model that can cause the dryer to stop heating. These are the most common:

  • Check for a tripped breaker. The dryer will run but won't heat, unless it has 120 volts to it. You can make this voltage check at the terminal block, across the black and red wires, on the back of the dryer. This will be where the power cord is connected.
  • Modern gas dryers use an electric igniter to ignite the gas from the gas valve. When it's working properly, the igniter glows bright orange. When it burns out, the dryer tumbles but there's no heat because the gas can't ignite.
  • Watch the igniter. Does it glow bright orange, then shut off without igniting the gas? (When the gas ignites there's a large blue flame.) If so, there may be defective coils on the gas valve. Mounted on the top of modern gas valves, there are black electrical coils. The coils, when energized, open the gas valve. If one or more of the coils are defective, the valve doesn't open and the gas cannot ignite.
  • On many dryers, there's a thermal fuse (a heat-sensitive fuse that blows if the dryer overheats) mounted to the exhaust duct inside the back cover panel. The fuse is about an inch long. It's usually embedded in black resin and mounted in a white plastic housing. If the fuse has blown, it has no continuity.

Other possibilities:

  • Timer
  • Thermostat
  • Door switch

Most of the components, need to be tested before you replace them. I would suggest that you have a technician do this, because is can be very complicated. You can schedule service at this website Sears Home Services . If you need further assistance, please reply to this thread. Thank you for using Manage My Life.

Thank you for your question and I understand your concern.

The glow bar ignitor should have a Blue and White connected to it. I added an image of the wiring diagram below to reference. They don't always label all wire colors on the wiring diagram. Look at the motor switch for additional color of wires. White connects between terminal 5M at the motor switch to gas valve solenoids and ignitor.

I hope this is helpful. If I may be of further assistance as more details become available, please reply to this post.
