Further Solutions You May Check

Here are a few more things as additional fixes that you may try to make your dryer’s proper working. Let’s check out.

Check The Air Flow

So, you must check the dryer vent for any clog disturbing the dryer’s working. The clogging prevents the airflow from passing through the dryer, which expands the spinning time.

So, it would be best to check the dryer’s venting system and remove any blockage once a year.

Check the Gas Valve Solenoid

check the gas valve solenoid

The quantity of gas valve solenoid coils depends on the model number you own. It might be twice or more.

The gas valve solenoids open the gas valve ports and enable the gas flow to pass through the burner assembly.

If the gas solenoids get defective, it may be possible that your dryer may not heat up properly. It may result in the form of continuous dryer runnings.

You must analyze the igniter to check the gas valve solenoid and whether these are fine or defective. If the igniter illuminates and turns off but is disabled to illuminate the gas, it’s a sign of a problem.

You have to analyze whether only one solenoid coil is defective or more. It would be better to replace coupled coils to resolve this issue.

Check The Blower Wheel

check the blower wheel

The blower wheel is responsible for inhaling air from the dryer and forcing out the air from the vent.

The bunch of lint and tiny particles from the clothes run away from the lint filter but are imprisoned in the blower wheel.

This component condition may cause a burnt or broken blower wheel sleeve. After that, the blower wheel wobbles the upper surface of the motor shaft.

As a result, the dryer extends the drying process, and the cause won’t stop the dryer. To inspect the wheel’s working, you must detach the vent and examine the airflow pressure.

If you suspect dull air flow, you must check the blower wheel for any blockage or interference. You may manually spin the wheel if you find no interference.

Inspect The Lint Filter

Check Heating Element or Assembly

So, the heating element and the assembly are responsible for warming the air before it gets into the dryer drum.

With time, one of them gets defective or burnt.

A burnt heating element or defective heating assembly may cause extra time to dry clothes compared to the normal cycle.

You may use a multimeter to inspect the heating element or heating element assembly.

Check The Cycling Thermostat

check the cycling thermostat

The cycling thermostat is responsible for monitoring the air temperature by turning On and Off the heat in the dryer.
