Tip & How-To about Dryers

Gas dryer no heat issue

This procedure and the videos will help you with 90% of all no heat issues in a gas dryer. But first we must first understand what needs to take place and in what order for the dryer to heat.

The dryer door must be closed and the door switch made.The dryer will not start until the switch signals that the door is closed.

A motor turns the clothes dryer drum and also turns a fan called a blower.
A gas dryer uses a burner assy. (see picture below) which has two solenoids/coils,a heat sensor and a igniter. Once the sensor acknloedges the heat from the igniter (it must reach a certain temp,safety factor) the sensor signals the coils to open up the gas valve which in turn is now ignited by the ignitor.


The dryer has thermostats that control the temperature in the unit. The unit acts almost exactly like your furnace does. When it gets below a certain temp the igniter turns on and when the temperature reaches the high limit the heat is turned off.

Those are the basics of how a dryer works.

The videos below will contain information that will allow you to check your dryers

No heat issue when the dryer/vent is clean (always do this first!)

Pull the dryer away from the wall. Disconnect the vent from the dryer. Turn the dryer on. If the dryer heats then you know your dryer vent is blocked and needs to be cleaned.If the vent is not blocked proceed to the video procedure below. When the dryer is taken apart look for blockage in the vent tube,wheel blower. Take this opportunity to clean your dryer completely.
A dirty clogged dryer is a fire hazard!



Just click on the links that pertain to your dryer type.

Rule of thumb for gas dryers...If the dryer turns but never produces heat then check the fuse.If the drum turns and you get intermittent heat,ignitor comes on but goes off without flame coming on or "my dryer takes longer to dry my clothes then check the gas valve coils first.

The first video is how to use and read your volt meter.This meter can be used for all appliance and electrical repairs in your home. It takes out all of the guess work on repairs. You can purchase one at your local hardware or lowes/homedepot for between $8.00 and $12.00

i have a kenmore 70 series gas dryer that stopped heating


Good day,
There are a lot of items that can cause a no heat condition on a gas dryer. Best to follow a step by step testing procedure to isolate the issue.

Here are items to check. You will need an ohm meter to perform some of these tests.
1. Make sure the gas is turned on to the appliance.
2. Remove the back cover of the dryer. In the center bottom is a small skinny white ceramic device, held on with one screw.
Remove one of the wires, and check it with an ohm meter. It should show zero ohms of resistance. If not, it is defective, and needs replaced. This device on your brand causes 80 to 90% of all no heat problems.
3. As well, there are 3 or 4 other thermostats in the area, either round or rectangular, with 2 wires going to them. Check all of them if needed. They should all check zero ohms.
4. To check the igniter, you will have to remove the front panel. A tutorial follows, on how to do that.
Locate the gas valve, on the left side. Follow it forward, you will see the 2 wires on a plug, and at the tip of the burner tube, the igniter itself. Unplug, and check the igniter leads. It should read about 20 to 30 ohms. if not, it has burned out and needs replaced.
5. On the gas valve itself, are 2 black coils, held on with a 2 screw bracket. They can fail, but cannot be tested with a meter. If they are bad, the heating system will light the igniter, and shut down without firing the gas. All components must be in place to perform this test.
That covers 99.5% of all issues. There are others, such as the timer, heat selector switch, centrifugal switch in the main motor, but are extremely rare.
The tutorial below is not about heat trouble shooting, but is supplied to show how to gain access to the front of the machine.

This is what the thermal fuse looks like. Common failure item, along with the ignitor.

The dryer will not get hot. We replaced the


Good day,
If one of the terminals from the flame sensor fell off and touched any part of the cabinet or other metal parts, it's possible it could have shorted out any component in the heating system, all the way back to the timer.
However, if not then a step by step procedure should get you there.

P.S. If the lead from the sensor fell, and shorted to the machine, as I said, the the gas coils may be totally destroyed and would not allow the ignitor to heat.
