How to Troubleshoot & Replace Whirlpool AP4011626 / 12200030 Grate Kit

I ordered a set of 2 new grates from Appliance Parts Pros. The grates were identical and my old Jenn Air looks like new with the new ones and it is great to cook with balanced pots and pans...no hot spots! I hope I can continue to replace parts to this old cook top as needed because it was made when appliances were made well and lasted! I really love this Jenn Air! Appliance Parts Pros customer service are great people! Due to problems from Whirlpool's shipping and packing I had to call Appliance Parts Pros customer service on three different occasions and they were so helpful and immediately re-ordered the parts again and again. The first shipment had one grate in it....it was supposed to be a set of two. The second shipment had two but they didn't wrap them in the bubble wrap individually or wrap the two tight so they wouldn't slide around so both rub against each other on the trip and rub the paint off to the silver core. The third time they ordered another set and they shipped one! But it worked because I still had the single one they sent the first time. It took over a month to receive my complete order! Whirlpool is the problem and unfortunately they bought Jenn Air, Maytag, Kitchen Aid, and many other great lines and Whirlpool used to be good but not anymore but they have all the parts for all the appliances! Thankfully I didn't have to deal with Whirlpool! Appliance Parts Pros handled it all in a very courteous, professional, and just plain good friendly people to work with! I will definitely be ordering more from them! The only suggestion I would make is when looking for the parts I need they don't have much of a description. I had the model # but because my appliance is old I wanted to be sure the size of the grates would fit even though the picture looked exact. They have a grid with the grate on it but when I counted the squares it was a little different then my old grate measurement. Which means if that was the true size it would be a little too big to set in the well. Customer service counted the grid too and came up with the same as I did. She thought it may be the measurement of the box so we ordered them. They were the correct size and fit as they should. But sizes in the description would be very helpful. Thank you Wendy, Scott, and Anita for all your help and being so nice! Great Service! Joanne H Fayetteville, NC 

I replaced the drip pans, grates, knobs, grease filter and downdraft grate. I have a new stove top! All for a fraction of the cost of a new one. 

They are wonderful!!!! I made the call to let them know my package was damage and they shipped me out new burners immediately and I received them the next day!!! Great great service! Can't say enough about there customer service!!!! Thank you! I will be sure to order again from you! 

Removed 4 old knobs and 4 old grates. Replace with 4 new knobs and 4 new grates. Took about 3 minutes. Stove looks new again (it's 29 years old) and works great. I can fry eggs (and other foods) and not have them run together, and not have oil in one side of the skillet. No more tippy pans. Very, very nice! 

Ordered new grates and a knob. 

Bought new fixtures
