I just replaced the bake ignitor in the bottom of the oven a few days ago. Worked fine the first few times I've used it.

Now, I pre-heated it to 350F, popped some food in. I immediately noticed the oven ignite again, go for 5-10 seconds, turn off, ignite for 5-10 seconds, turn off. It did this three or four times. I turned the oven off, waited a few seconds and turned it back to 350. Beeped at 350 immediately. I stood there for about a minute and didn't notice anything strange. Checked it periodically over the 25 min bake and didn't notice anything. It ignited every 2-3 minutes for 10-15 seconds each time, which is about normal for that oven.

Wondering what could have caused the strange behavior, and if there is anything I should check or be worried about.

edit: Used the oven later in the day, and it did it for the entire 30 minutes the oven was on. After oven was heated, it would ignite and heat for about 20 seconds, turn off for about a minute, then ignite again. It ignited probably 20 times during the 25 minutes it took to bake a pizza.

Door is fine.

There is a vent under the control panel that puts out some heat. I never paid much attention to it before, so I'm not sure how hot the air coming out of it should be. It feels a bit excessive. I can put my hand just past the back burners and the heat from the vent is uncomfortable. If I put my hand a few inches from the vent, it hurts a bit.

Also, the model is actually MGR5775QDB.
