Hi. Pretty sure my torsion spring (one or both) has failed. I guess I was lucky that the glass didn't fracture but this is maybe still a possibility w/ heat cycle?

Anyways, I'm confused on the part#. I brought up the parts list here for this model# and I get:

38A Microwave door torsion spring - For stainless models. Left hand side. For the right hand side order AP3082257. No color tip. 49.5 - 54.5 lbs torque. Size: 3.50 inches long.
Item Number: AP3137553
Manufacturer's Number: 4452395 made by WHIRLPOOL

38B Microwave door torsion spring - Right hand side. For the left hand side order AP3137553. No color code on tip.
Item Number: AP3126615
Manufacturer's Number: 4452398 made by WHIRLPOOL


What is line 38A trying to tell me about the right side? To use AP3082257 in preference to AP3126615 for stainless???


I asked APP via online chat and they told me for stainless that I needed:
38A 4452395 AP3137553
38B 4452398 AP3126615

I'm fairly confused here. Can anyone clarify.

I've owned unit since new, over 5 years and this is the first failure. I've read a bunch of reports of repeated spring failures and of door not having original tension after springs are replaced .... so if there are better springs to use I'd be interested in hearing, read some other threads where KitchenAid had recommended using two medium springs but validity of advice was questioned.

Thanks .... so what is the deal with 4452396/AP3082257

It's all very confusing.
