Dryer will not dry clothes.
I assume it runs and this is from that stance. If it doesn't the motor has to be checked and the power coming in. In fact the dryer can run and still not have the correct power to opperate the heater.
Assuming you have a volt meter and know how to use it properly.
These are the steps that the power and machine have to take to operate properly
A. If the dryer has all of these things it has to be heating and an air
flow problem (kinked or dirty dryer duck, motor fan clogged with lint,
vent flapper not opening...) is suspect.
1. power is correct (USA 220V across line and 115v to ground/neut) 2 hot lines with potential between them and a neutral and possible a ground
2 Door switch is closed
3 Timer switch closes and ready s power to heating element through centrifugal switch in the motor circuit after the motor is running.
4 the heating element is assumed to be good and have 220v at this point. Checking for voltage at the element will assure all before are ok and at least allowing the heater to work.
5 the heating element is controlled by 1 or more thermostats and a safety thermostat. If either of these switches do not close when the dryer is "cool" they are bad. NOTE some dryers could ahve 3 wire thermostats. These can read closed on one set and open on the other. And this is how they should be if good. But tracing the wire diagram will tell which set is closed and when.
6 if you have power, the timer contacts to the motor and the heater (separate circuits usually)are "closed", the motor runs, the cent switch "closes", the temperature operating thermostats are closed, and the heating element is good you have to have heat.
1 Check for 220V power into the dryer. If not check breakers and turn off and on several time pushing them firmly. If this is ok and 220V present step 1 is done.
2 This assumes the motor will run
