Rod,

Have you checked the venting system for kinked venting or lint clogging the pipe, or vent hood ?

You could also discconnect the exhaust vent from the back of the dryer and check for how long it takes to dry a load of clothes, that would help varify a clogged vent system.

When coils become weak and start to malfunction,
Yes you will get a similar symptom, but that's why you need to eliminate the vent system first.

Here is the part number for both coils for the gas valve(should you need them).

Part number: AP3094251

Rod,

A clogged or kinked vent, lint filter,etc. will cause the dryer to heat too quickly, and give the impression of a low temperature in the dryer and take too long to dry.

A weak set of gas valve coils, will cause a simillar symptom, the coils get weak and there is no gas released near the end of the cycle,giving the impression of a low heat, takes too long to dry.

These problems are more common than a bad thermostat or temperature selector switch.

That's why I reccomended you observe the gas valve operation and flame through the inspection openning in the front panel with a load in the dryer and the vent disconnected.

You can check circuits on the temperature switch and thermostat if you have a multi meter.

At the switch, with both purple wires off, you should read approximately 10 ohms resistance on the low setting and 10,000 ohms resistance on the high heat setting. if your resistance remains at 10 ohms when the switch is on the high setting, you'd have a bad switch.

Rod,

You're quite welcome,

Happy Thanksgiving
