Product review (1 stars): Beware!
I bought two 6 inch burners from this company and they were exactly right for my 17 year old Whirlpool cook top.  Because I had already purchased the 8 inch elements from two other companies and neither were the proper replacement, I emailed North American HVAC BEFORE ordering to ask if the 8 inch were a perfect match to the 6 inch except for size.  I was told that they were identical.  Still, I was skeptical and decided to order only ONE.

Imagine my surprise when it arrived (with no wrapping other than a thin bubble-wrap envelop) and found that the burner was green, the plug-in ends were solid instead of an open loop and the other end that anchors the burner was blunt instead of pointed.  I wrote NA HVAC twice for an explanation.  They wrote back and said the green would burn off after use, the solid plug-ins were "compatible" with the open loop configuration, etc.

I think when a company tells you something is an exact match to a previously purchased item, that it should be.  I requested a return.  They agreed to "waive the re-stocking fee."  WHAT???  But I had to package, insure and ship the product back at MY expense.  I will not trust this vendor again.

I have since purchased the correct replacement burner from another AMZN vendor (Supply Edge) for a lesser amount and it has arrived.  It IS the exact match to the 6 inch and even has the part number stamped on it.  Today I ordered the 2nd one from Supply Edge.  And, I used all their bubble wrap and cardboard pieces for the return of the wrong one.  Supply Edge knows how to ship a fragile element.  North American HVAC is just BS!
