whirlpool gas dryer - no high heat

Whirlpool Gas Dryer model# LGR4634EQ0

Heat comes on only in "low heat" cycle.

I have already changed the igniter element and glow sensor, which were both defective. Now the unit operates, but only in low heat cycle.

I replace part#3387134, (recommended at parts store) which appeared to be a thermostat. Still no high heat.

Hello K Perez. Welcome to my Gas Appliances forum and our Do-It-Yourself Web Site.

The ignitor and glow sensor having already been replaced and do not control temperature, at least those parts are new. Be sure all connections already made to the newly installed parts are correct. Double check them if need be or not sure.

What now needs to be checked is the heat selector switch. The temperature selector switch may have internally defective contact points in it, loose connections into it, out of it or any other part connected to it.

The temperature control sensors may be defective. They should be located on the fan blowers housing. There is also a moisture sensor and a high limit temp sensor. Any one of them could be defective and or inoperative.

Sensors can be checked for electrical continutiy using a ohm meter. So can the temp selector switche. Be sure the electrical power to the appliance is turned off or the appliance is unpluged from the wall recepticule.

Read the manufacturers online web site for product information, problem possibilities, causes and solving methods, part locations, disassembly, reassembly methods, repair proceedures and instructions, pictorials and schematics, which may be available online.

The do-it-yourself person can do electrical tests and continuity tests on several electrical parts. However, I do not recommend relying solely on either test to determine if any electrical or electronic part or parts are causing the problem. The idea is not to replace costly parts until the defective one is found.

The only positive proof any part is functioning correctly, is to carefully remove the part or parts you suspect to be the potential problems, and have the local appliance parts store person test it or check it. Appliance parts dealers carry replacement parts for all appliances and are listed in the phone book under appliances.

It's always adviseable to clean the entire exhaust venting system every 2 years and or during any dryer maintenance and or repairs.
