Disconnected exhaust vent pipe. Removed lower front panel. Turn on dryer, hear clacking noise, but nothing happens. No flame, nothing glows and no heat to dryer. I've replaced the Radiant Sensor, Thermostat and ignitor coils - still no luck. What else could it be??????

Hello wiz. Welcome to my Gas Appliances forum and our Do-It-Yourself Web Site.
Dryers that fail to heat can have any one of several causes.
Most likely the hot surface glow ignitor is burned out. Check for electrical current at the quick connection wire to the ignitor.
The next most likely parts are those on top of the gas valve. They are the solenoids.
When one of them gets heated too much from normal usage, the coils of wire within them expand and break the internal electrical connection. Solenoid replacement is the only correctional option.
Replacing the solenoids, which are sold in pairs only, should resolve the problem. Be sure to unplug the dryer first and turn off the gas supply to it before attempting any repairs.
Remove the entire gas valve assembly. Then remove both solenoids off the gas valve body by removing the hold down cover plate. Replace both solenoids and reassemble the parts as you originally found them
Or take the entire gas valve unit to your local appliance parts store and have the entire assembly and all the parts tested individually and as an assembly.
Another possibility could be a defective gas valve. Remove entire gas valve unit as an assembly. Take the entire assembly to your local appliance parts store for testing. Gas valves are not repairable. Replacement is the only option, if the gas valve is found to be defective.
Flame Sensor is yet another possibility:
This part is located on the burner housing. If it's defective, it may cause the problem your discribing. You can test this part with a continuity tester or an ohm meter.
A weak glow coil may also be all or part of the problem. Replacing it may resolve the problem but not positively.
For additional information, repair instructions etc. read the other questions within this forum pertaining to dryer topics. The questions already asked describe like or similarly related problem descriptions as your question.
These prior postings and any or all the replies offered within them contain all the required information needed pertaining to the many possible problems with the dryers unit like your describing.
Retail appliance parts dealers can also help determine what the possible problem may be. Bring the make, model & serial numbers.
Appliance parts dealers are an excellent source for additional problem solving information and original replacement parts. Parts dealers are listed in the phone book.
Tips:
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 positively 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.
If you need further assistance, use the REPLY button once again to add any additional information or ask additional questions after attempting the correctional method or methods offered.
