My dryer runs, but will not heat. I have checked continuity on all thermostats, and thermal fuse. All are good. I have replaced the hi-temp cutoff, and high limit thermostat. The heater element shows continuity and no breaks in the wires. I've also checked the motor terminal block and everything appears to be working properly (i.e. no binding, clean of dust). Every once in a while, the dryer will heat, so I'm pretty sure that the heating system still works, but I cannot determine what is causing this.
There are 2 components other than the thermostats which would cause the heating element not to work. First is the motor and second the timer. The best option is to disconnect the power to the unit and access the heating element. Disconnect one wire that is going to the heating element, preferably the one on the thermostat side. Plug the unit back up and using a multimeter you will want to turn the dryer on and test for 120 vac at the terminal on the heater where the wire was disconnected. What this will do is eliminate the heater element itself and the motor. If there is 120 vac at this point then you know the heater is good and the motor is good because the other 120 vac coming through the thermostats is the timer side of the circuit. If there is not 120 vac at that point then you will want to test the other terminal on the heater and check for 120 vac. If there is not 120 vac then the motor would be bad and if there is 120 vac then the heater would be the issue. If there is 120 vac at each point then the heater is faulty.
I have a Whirlpool gas dryer (wgd4800xq0) that will not fire up. I have checked all the thermostats and thermal cutout.It does not even attempt to fire up. Any idea what could be causing this?
Answer Hello Ahale. You will need to test the thermostats and the flame sensor and make sure they are good. They should read closed for continuity. Also, check the igniter and make sure it is getting hot enough to light the gas. If it is not glowing, test for power. Here is a link on how to use a multi-meter for the testing procedures. http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html
Dryer will heat in auto-dry but will not heat in timed-dry. Coud it be the timer and how do I check for a bad timer?
The timer could be the issue if the contacts are not making to complete the heat circuit. To test the timer you will do a voltage test. You check from Black to Red wires on the timer. If you are getting 240 vac then the timer is faulty and would need to be replaced.
I'm troubleshooting my dryer for not heating. All thermostats check OK. It appears the timer may be bad. My question is; Is the heating element supposed to cycle on and off while drying?
Answer Hi Joe, yes the element is supposed to cycle on and off with the help of a cycling thermostat. There are several thermostats and a thermal fuse on your dryer. If any of those failed, it would interrupt power to the element. If the element works, check your vent for a blockage. Clogged vents keep a dryer from heating well and can eventually cause a hi-limit or thermal fuse failure. Also, you didn't mention it but is your drum turning? If not, you need to check your belt.

Where can I get the instructions on how to change the timer?
Answer Hello Andres,
First and most important, unplug the unit from its' power supply. Then remove the six screws holding the control panel back on and pull the knob off. Now it's really important not to remove the wires yet as you will do that one at a time as you install them on the new timer. You do this to prevent cross-wiring the timer and costing yourself time and money.
Now there should be two 1/4 inch hex head screws holding the timer in position. With these removed, you will have enough slack in the wiring to hold the new timer next to it for "one wire at a time" wire replacement. Once all of the wires have been transferred to the new timer, reinstall the two 1/4 inch hex head screws and the knob. Reinstall the back panel cover and test the unit.
