What an incredible deal! If you have tested your sail switch and that's not the problem then just buy this and be done with it. Slips right in old sleeve and works great! This is upgraded and it is surprisingly more powerful and much more quiet than the 10-year-old model that is in my RV. Worth every penny! Don't bother replacing your motor or control board if your heater is already 7 years old or older you'll just start having other problems with it especially if it's in a RV that is lived in like a park model and used frequently just upgrade just buy this and put it in it's an upgrade all the way around
