Hello. My Rheem furnace needs a new pressure switch. The broken switch is from Amazon seller, and it lasted almost 3 years. I checked back and the same switches are for sale. Having to spend $50 for another same switch is...
I looked around, and Lennox has a switch that is rated .31 wc-pf. The Rheem switch is .30" wc.
I called Rheem and asked in hvac forums, but it is by the script, which is can't answer for variances.
Does .01" wc matter that much?
I don't know the electrical rating for Lennox switch, but I could ask the seller, I hope.
Thank you in advance.
