Whirlpool dryer 7929 inglis

Hello there and welcome to fixya there are several things that could make this dryer not heat up
Here are the most common things

Thermal Fuse

If the dryer doesn\'t heat, but the drum
turns, check the thermal fuse(s). The thermal fuse protects the dryer
from overheating and helps to prevent fires. If the thermal fuse is
blown, it will have to be replaced.

Gas Valve Solenoid

The gas valve has two or more electric
solenoids which open the valve to let the gas flow into the burner
assembly. If the dryer doesn\'t heat one or more of the solenoids may be
defective. If the igniter glows for 90 seconds but the burner flame
doesn\'t light, replace these coils as a set.


Dryer Igniter


If the dryer doesn\'t heat, the igniter might
be burned out. Check the igniter for continuity with an ohm meter. Dryer
igniters burn out over time, similar to a light bulb.

Heating Element

The heating element on an electric dryer can
burn out over time. If the dryer doesn\'t heat, the element should be
checked for continuity. The heating element cannot be repaired and must
be replaced if defective.

Heating Element Assembly

the heating element assembly on an electric
dryer can burn out over time. If the dryer doesn\'t heat, the element
assembly should be checked for continuity. The heating element assembly
cannot be repaired and must be replaced if defective.

Flame Sensor



Gas dryers have a flame sensor to detect the
heat given off by the flame. If the dryer doesn\'t heat, the flame sensor
might be defective. Check the flame sensor for continuity. This is not
as common as a burned out igniter or thermal fuse.


High Limit Thermostat


Although not common, if the dryer doesn\'t
heat the high limit thermostat can be defective. It can be checked for
continuity. If the thermostat is "open" the dryer doesn\'t heat.


Cycling Thermostat




The cycling thermostat regulates the
temperature of the air in the dryer. If the dryer doesn\'t heat it may be
caused by a defective cycling thermostat. This is not common.


Main Control Board

The main control board is normally not at
fault when the dryer doesn\'t heat. Check all of the other components in
this troubleshooting guide before replacing the main control board. The
main control board cannot be tested easily and must be replaced if it is
defective.


Timer
The timer is normally not at fault if the
dryer doesn\'t heat. In many situations where timers are replaced they
end up being returned. Check all of the more common components in this
troubleshooting guide before replacing the timer

there is a cycling thermostat in line with the high limit thermostat and timer circuit,on timed dry its disabled and the timer will run no matter what,on any sensor dry setting it uses the heat of the element to heat this cycling thermostat to move the timer as the clothes get drier as the heating element heats the timer doesn't move,when the heater cycles off from the high limit thermostat then timer moves again,you need to find out if its a bad heating element,thermal fuse or possibly even a circuit breaker in the homes electrical panel tripped out on one of the 2 phases that gives you the 240 volts required to operate the dryer element,the breaker may not show its tripped,so shut it off and back on and try this first

See if you can spin the drum with little resistance or is it really hard to spin?

A dryer runs 2 halfs (one half 120, the other 120). Sounds like you are missing the 120 that operates those two. Did you change from a four prong to a three prong?

The way to visually see if the belt has broken or not is to 1) unplug the dryer. 2) Remove the lint screen on the top of the dryer. 3) take the two phillips head screws out where the lint trap is. 4) with a flat head screwdriver pop the top of the dryer up by sliding the driver inbetween the top and front of the dryer and pry upwards a little. 5) You'll now see the drum, if the belt is not around it its broken, and if it's visible try to lift it. If it taught, its good. IF THE BELT IS BROKEN OR LOOSE CONTINUE TO NEXT STEPS 6) on the left and right upper inner sides of the dryer you will find two screws, one on each side, remove these and the front should be easlily remove. 7) once off you'll be able to easily see the motor, the belts idler pulley, and everything else.

No heat indicates a burned out heating element.Easily replaced.Cant answer on timer.

Make sure you have 240 going into the dryer. If one side of the breaker is tripped it is posible for the dryer to run because the motor runs on 120 volts ac. The heat uses 240 volts. Next check the heavy red wire coming out of the timer. Remove it from the timer and attach a lead from an ohm meter to that leg on the timer. See if you can get a reading from any other leg on that timer. Move the dil to various spots on the timer and keep checking for continuity. If you cannot get a reading from that terminal to any other terminal on the dryer then you have a bad timer.
I did a few homemade movies today and posted them on my youtube channel:

Hello, welcome to FixYa.

Based on your post I understand you have a Whirlpool dryer that you stated "set the timer and press the start button, you can hear the timer running but, the drum doesn't and the heating elements don't heat", correct ?

Having said that, by far and away the most common and the first thing I'd look for on these dryers is the fuse which is located on the blower housing, not likely the timer or start switch.

**Unplug the dryer from the wall before performing any service or removing any panels...safety first**

You can use the link below for a tutorial video to locate, test and replace the fuse that is specific to your model.
**please check the part with an ohm meter or "jump it out" (if you know how, if not, check the second link it will show you) before replacing it...the timer or start switch is possible, just not as likely as I mentioned**
