For that unit all you need is a 2 pole 40 amp 24 volt contactor. Just a standard replacement contactor. Russ
Do you happen to know a grainger number
If not the part # XXXXX approxiamate cost?
Go to www.americanhvacparts.com Type CTR40242PSD tope right. A picture of the part will come up. Do not buy it here. Cost about twice what a contactor should cost. Should be no more than 25 dollars. If you google 24 volt contactor dozens of sites will come up.Russ
Thanks great job. I hope this gig does well for you
