I called Cleveland Controls and they gave me the updated number. Called Supply House and she verified it was the correct replacement part. We had a huge ice storm that took out or electrical grid. I noticed short cycling on generator power. Jumped switch until part came. It was here in 2 days but UPS wasn't delivering to our county because of grid issues and I told them it was a part for my hot water boiler. They delivered the following morning! Thank Supply House, your team is fantastic!
