Hi, one insert on the cook top is showing signs of wear of the left side terminal block. I have to push the dual burner cartridge in just right for the burners to operate. The two sets of burner cartridges work fine on the left side, and I recently purchased two new burner cartridge assemblies, so confident its not the cartridges. I believe the block assembly is Cooktop Grill Element Receptacle WPY702434.

Can the block be removed without taking the cook top off the counter, or can be done in place? Anyone know the part number for the terminals in the block, I am guessing its the terminals that need replacing not the ceramic block. thanks in advance.

Do not use a cartridge in a location with questionable contact or the cartridge terminals may be damaged. Any cartridge terminals that show signs of discoloration could damage the mating terminals in the cooktop receptacle. Any discolored cartridge terminals should be replaced.

I am guessing its the terminals that need replacing not the ceramic block.

Yes, unfortunately the contacts are discontinued and NLA. I did find some new/old stock available at the following link.

Here's a better photo of what that part consists of:

Can the block be removed without taking the cook top off the counter

I believe the whole cooktop needs to be removed (or at least raised) to access those parts.

Thanks, I ordered the parts

I'm glad I found that one. It might be the last one in existence.

If you get a chance, let us know how you make out.

Is it unlikely the ceramic receptacle is damaged? or should I order one as well? I would hate to have it all apart and find the ceramic is cracked and have to wait for a new one.

Is it unlikely the ceramic receptacle is damaged?

I've never seen the ceramic receptacle ever been needed unless damaged during service. There's no wear and tear on it so unless you damage it, it is unlikely to be required.

@Dan O. Thanks for all info in Nov. The cooktop insert worked when I pushed it into the terminals , so I put off changing the contacts. Yesterday, it stopped working, so I pull the cook top off the counter, disassembled, it was easier than I thought to pull the top off the counter. Taking the top off the counter took all of 15 min.

I removed the terminal block. Looking at the old block and contacts, the contacts on the replacement kit seem to have the threaded receiver for harness lugs 90 degrees different than the original. A few questions:

Can the contacts be used, by bending the lugs on the harness 90 degrees?

Is there a special too to extract the old contact from the ceramic? I tried slipping two thin adhesive spatulas on either side of the contact, thinking it was compress the tabs and extract, like a Molnex connector tool, but the contact didn't really move, so I didn't force it.

Last night I used an old Ignition Point file, and cleaned the contact that looked dirty, reassembled the cook top and the insert is working.

I would still like to replace the contacts, I anyone has tips, please let me know, I can post photos if my description is hard to follow.

Do you mean just where the wiring attaches to the contact? If so, those can probably be modified.

If the original contacts weren't in too bad of shape and you were able to clean them up, I might leave them as they are. If you're not swapping cartridges often, there isn't much wear and tear on them. If the metal was physically burned or melted, definitely replace them.

Not to my knowledge.

@Dan O. Are there any tricks to removing the contacts from the Ceramic? Someone was selling an old harness on eBay for this cook top, I bought it. I thought with parts obsolete, it can't hurt, and I can practice installing and install the contacts.

 

[Dan O.]

No, there are no tricks or special tools that should be required. I'm afraid I can't tell you how to go about it though. I imagine compress the contact and it should come free.

I got lucky with the eBay purchase. The ceramic, and contacts look like new, no sign of burning or pitting on the contacts. The harness is intact with spade connectors. I'll keep as a spare, if the insert acts intermittent again, I will do a remove and replace of the ceramic and harness.

 

[Dan O.]

Sounds like a plan. Thanks for the followup.
