Product review (5 stars): Replacement not always necessary.
This review is not from a verified purchase because I didn't need to purchase one. Read on.

Are you experiencing a condition where the oven lights and immediately goes out? Yes, we did. Does the oven retry 3 times and then lockout? Yes, it does.

Save yourself the money. The problem most likely is a fault detected in the rectification/flame sensing circuit. It's actually not a 'fault'. It's a safety circuit functioning properly.

This is not a big deal to restore normal operation. Anyone with minor mechanical skills can handle it.

Simply remove the igniter, gently wipe the darkened part of the tip with emery cloth or steel wool to remove the 'very' thin layer of carbon that accumulated to restore it to a bright luster.

Reinstall and test. In most cases this should restore the stove to normal operation.

Check youtube for your model for details on removing and reinstalling. It's simple. 15 mins typical.

It is infuriating that the manufacturers do not include this simple task in the owners manuals troubleshooting section. I guess they would rather sell a part than explain what could/should be a routine maintenance task, like cleaning the oven itself.

This is one of a number of tasks that should be done as routine maintenance on your gas furnace or cold water heater. I wouldn't be surprised if unsavory HVAC and plumbing and heating outfits are taking advantage of people claiming to replace a part they merely clean as part of annual system maintenance.
