Was exact replacement but also had a separate cover the other one didn’t have!

My old ” new” one failed after about 2 holidays. So 3 weeks of use the rest of the time the RV was parked and shut down. The price is what you should pay for a mass produced electronic board and the sensor plus wires. It is great that it comes with a cover to protect it from water. My only complaint is that the supplied wires are a little short. But that being said it is worth the cost to replace your faulty one. Price is half of what others want.

It would have got an excellent review but no instructions were included. It was identical to the existing unit and I only had to find were the thermocouple was located and replace it. It plugged right into to old receiver switch which was still operating. I placed the new cover and I now have a spare switch.
