Tip & How-To about Dryers
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!

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.
