How to Troubleshoot & Replace Whirlpool AP6011414 / WP7527P021-60 Orifice Holder (16K)

Replaced switch assembly 

In an attempt to clean the range from the grease-gunk build-up, I had to remove the burner heads. Unfortunately, the 2 most used burner heads had immovable screws that locked them into the orifices underneath. After numerous hours in attempts to salvage the old burner heads and orifices attempting to remove the immovable screws, I gave up. Checked Maytag's website for parts and found nothing. Turned to AppliancePartsPros.com and found the correct parts for reasonable price in a matter of minutes. Good to know that there are places like this out there in case I ever get into a mess like this again... 

I had to drill out the screws that hold down the burner plates which also mount to the orifice holders because all of the screws had rusted tight and could not be loosened. The drilling out part was fairly easy and once I had removed the burner plates, I could easily lift the stove top off and get access to the orifice holders to replace all of them. I purchased new stainless steel self-threading screws from our local hardware store and re-assembled the new orifice holders and existing burner plates. I was very careful in drilling out the screws and did not damage any of the burner plates. Lastly, I had to access the gas regulator in the back of the oven to remove the plug and flip over the plug to switch the regulator to NG. The burners all work very well and I saved myself $250-300 in labor quoted by a contractor. The contractor was also going to charge me about $60 more for the orifice holders than I paid for the parts from Appliance Parts.com 

Ordered the parts from appliance parts pros and installed parts I did have to drill out the existing screws holding the existing orfice holders as the existing screws were rusted out 

Ordered ignitor harness and two burners (Holder/Orifice) and with supplied videos spent about 40 minutes exchanging parts - saved roughly $500. Must say, great parts (look original), good price, easy web site and, most of all, helpful video! 

When removing the burner plates the self-taping screws broke off at the head leaving the majority of the screw frozen in place. Once I was able to see the gas burner orifice holder it was plain to see that the years of heat cycles and moisture had taken a toll on these screws. The Vise-grips and penetrating oils were not able to free up the screw for removal, the next option was to replace the Holder, orifice. Note that there are 4 sizes of this part, double check you are buying the correct part. 

Replaced both bake elements and left front burner 

I purchased the new orifice holders that are complete with the orifices and igniters from AppliancePartsPros.com. They were easy to swap out. 

Replaced holder /orifice. The only problem with this fix was all of the screws holding the burners in place were rusted and had to be drilled to access the part to replace. So I had to replace all 5 of the Holder/orifice. Relatively easy fix. 

Tried to clean the burner heads but couldn’t remove screws. Cleaned them while on stove but didn’t help the uneven flames.Purchased four new orfice holders.all the screws in burner heads broke.tried to remove with left handed drill and tried ez outs with no avail. Hence the purchase of new orfice holders. used a self tapping screw to make threads in the holders before installing and made it easier to attach burner heads after installing the orfice holders. All flames burn like they did when the range was new and wife is happy and I didn’t have to buy a new range.
