Whirlpool WP7527P028-60 Orifice Holder (12K Burner) OEM Part

The top had to be removed but with the unit being 14 years old, galvanic corrosion had seized the screws holding the Burner Heads to the Orifices. I carefully drilled out the heads of the screws until the Burner heads could be pulled free. I removed the two screws that held the Burner control assembly with all the gas valves in place. If you open the top oven, there are two last screws that thread straight up into the top. So 14 screws in all. I ordered 10 new screws along with the Orifices that had been drilled out.. a 16K, 12K and two 5K. What was shipped was for Natural gas so I had to swap back in the LP nozzles from the old orifices.. but got clean new screw surfaces and new spark electrodes in the process. I removed all the spark electrodes before assembly and replaced the screws holding them with stainless steel threaded in with anti-seize. I used an impact screwdriver to get the old screws out so I could reuse the plastic spark shields. While the top was off, I hit some rust spots with phosphoric acid and sprayed with gloss black engine paint (good for high heat). I test threaded the 10 new bolts in the orifices', then bolted the tubes back up. I replaced the top and bolted down the Burner heads and burner valve control assembly. The two screws just under the front were rusty so I replaced them with stainless as well. All 14 screws replaced and anti-seized, as well as the five holding the spark ignitors. Four of the ignitors worked fine after reassembly, but the front right still refuses to ignite. No spark sound from that one.. but the rest spark so the spark module must be good. Apparently, I have to replace ignition switches too. That will be a cakewalk after all the prep I did to make sure it comes apart and goes together again. One note. There was a green ground wire with a washer under the back valve assembly that is difficult to keep in place as you replace the top.. It just sits there waiting for the second screw that holds the burner valve control assembly.. so I crimped a SECOND washer end on the wire forming a top and bottom ring that CLIPPED into place - that held if firmly enough that the wire was NOT disturbed while I juggled the top into place. That way I could get the screw through the hole in the top, through the ground wire ring, and still thread into the burner valve assemble, securing t to the top.

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

I replaced the Igniter switch, two control valves and one holder/orifice (because I couldn't get the screws out and decided to just replace it rather than re-tape it and get new screws). The one thing I forgot was I have propane and the orifice was for natural gas. Fortunately, I was able to swap out the orifice from the old holder.

We've had this range for several years and love the gas cook top with dual electric ovens with convection bake. I've looked and could not get another like it for an affordable price. Some of the burners stopped lighting from the igniter and an oven element was sagging. The diagrams and associated parts list made it easy to locate the correct parts. Delivery was faster thank I expected. I had the repairs done and the range back to 100% before my wife had a chance to roll her eyes. I documented all my notes, parts, model numbers, etc. With confidence that I can manage future repairs, I look forward to keeping this range in service for years to come.
