Dryer runs but doesn't heat.

Your timer most likely does need to be replaced. The timer has a small motor that causes it to rotate during the cycle and those can go bad causing the timer to not advance. Unfortunately, you cannot get just that timer motor anymore. Hope this helps!

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

Instructions

1. • 1 Check the cycle selector control to make sure a heating cycle has been selected. The selector should be in an "Off" position when not in use, but it should be turned to a drying cycle when in use. On some models, make sure you are not accidentally running the dryer on the "Air" cycle, which does not use heat.
     
   • 2 Check the gas supply valve to make sure it is open if your dryer is a gas dryer. If it is not open, just lift the valve open.
     
   • 3 Look at your house's main breaker box to determine whether a circuit breaker is tripped. The electric dryer runs on 220-240 volts and has a double breaker. If the breaker for the heating element is tripped, the drum may tumble the clothes without heat. Turn the dryer's breakers to off, then back on; test whether the dryer will produce heat.
     
   • 4 Consult a technician if troubleshooting does not resolve the problem.
     

Hi.

If machine runs only in low heath cycles, then there is a problem with timer control, low heath selector, or heating assembly (cycling thermostat).

The first thing to do would be locating the tech sheet. The sheet is tucked inside an envelope located inside the control panel assembly. In the tech sheet you will find instructions to run a diagnostic cycle. The diagnostic cycle will return an error code that will help locating the fault.

With different Frigidaire Affinity dryers you need to press and hold Pause Cancel and SELECT for about ten seconds, then leave, put selector to NORMAL, temperature selector to HIGH HEAT and touch START to run the diagnostic cycle. The procedure for this specific model is described in the tech sheet.

Hi,

This is this is the "program Timeout Fault". Meaning the drying time has exceeded program time for that cycle.Press Pause Cancel and SELECT buttons for 6 seconds to exit test modes. Position cycle selector to NORMAL, temperature selector to HIGH HEAT and touch START. Check for anything that would extend dry times such as: no heat, restricted vent, blower fan blade broken or loose, dryer installed in closet with solid door, or bad connection in moisture sensor bar circuit or dirty bars. If dryer operates normally but code returns, replace electronic control.
Hope i helped you.

Thanks for using ' Fixya ' and have a nice day!!

One of the switches that controls the heating element has not closed.

sounds like a bad cycle timer switch

Q - My electric dryer runs but will not heat, what could stop my dryer from heating?
A - Things that could stop a electric dryer from heating:
- house fuse or breaker ( needs two of them ), heating element, burnt wire, thermostat(s), thermal fuse ( not all models ), motor heat switch, timer, selector switch, burnt power cord/plug.
A ohm meter test for these parts is here.

CHECK FOR 240VOLTS AT THE OUTLET. A DRYER WILL RUN ON HALF THE 240 VOLT CIRCUIT BUT WON'T HEAT.
IF THE VOLTAGE IS THERE, CHECK FOR 240 VOLTS AT THE HEATER. IF IT IS THERE AT THE TERMINALS OF THE HEATER, AND THERE IS NO HEAT, THE HEATER IS BAD.
IF NO VOLTAGE IS PRESENT, TRACE BACKWARDS THROUGH THE HEAT CIRCUIT AND CHECK EACH COMPONENT IN THAT CIRCUIT. IF ONE OF THEM HAS 240 VOLTS PRESENT, THAT IS THE BAD COMPONENT.
POSSIBILITIES ARE, HIGH LIMIT THERMOSTAT, CYCLING THERMOSTAT, THERMAL FUSE, MOTOR CENTRIFUGAL SWITCH, HEAT SELECTOR SWITCH, TIMER. POWER CORD.
