Amana AGS781E Gas Range

Hi...I'm new to the forum and think this is a great site.

I have an Amana AGS781E natural gas range and have a problem with the broil function. When selecting 'broil', the broil ignitor does not glow at all. My guess is to replace the ignitor. I'm curious about the fact that gas is not admitted to the burner up there a safety feature that prevents gas from being admitted because the ignitor does not fire? How is this done? Is there a way to diagnose a failed ignitor using a multimeter? Any assistance would be appreciated.

Hello topgun_tb. Welcome to my Gas Appliances topic and the Do-It-Yourself Web Site.

If the glow bar igniter is glowing and the burner fails to light, most likely the glowing hot surface igniter is too weak to provide enough of an ignition source. That being the most likely problem cause, replacing the glow igniter will resolve the problem.

A hot glowing surface igniter, working correctly, will glow an intense bright yellow orange in color. Any reddish color or a dull orange color indicates the glow coil is weak.

If the igniter fails to glow at all and all other selections and optional selections on the control panel are set correctly, the hot surface igniter will need to be replaced with a new part. Replacing it should solve the problem.

Ovens with touch pad controls use electronic computerized circuit boards. The entire circuit board could be removed and taken to the local appliance parts dealer for testing and or replacement.

Before attempting any repairs, be sure to unplug the appliance from the wall receptacle power source first.

For more detailed information etc. read the recent postings within this forum. The questions already asked describe like or similarly related problem descriptions as your question.

These prior postings and all the replies offered within them contain almost all the required information needed to the many possible problems with an ovens hot surface ignition system.

Retail appliance parts dealers can also help determine what the possible problem may be also. They will need the make, model an serial numbers. Appliance parts dealers are an excellent source for original replacement parts. Dealers are listed in the phone book under appliances.

The ignitor can be checked with an ohm meter. Disconnect the two wires going to the ignitor and check for continuity. A properly functioning ignitor should read 30 to 50 ohms.

With the sympoms you describe I would suspect the ignitor. Don't be suprised you are not getting gas flow with the ignitor not working. The voltage traveling through the ignitor goes into the oven safety valve and allows the safety to open. If the oven safety is not getting voltage due to a failed ignitor, it will not allow gas through.

Thanks for the replies. I'll pull the failed ignitor out and check it's resistance.
