Product review (1 stars): Try to BLUE WIRED ones!
Product delivered was defective... appears to be the case with most of these per the reviews.  Complete crap that you can't test a solenoid before shipping.... two wires, 2.4 volts... should be pretty easy to make sure it works.  I'll be sending back for a refund and will go with someone else.  I'd suggest other buyers try the "blue wired" one as I tried to match and well... here we are.  And this was confirmed via a $65 5 minute HVAC visit to confirm it was indeed the solenoid that was defective.  Can't send that $65 back for a refund though...
