Review: Perfect replacement for my ageing furnace with a sticky sail switch - Fit perfectly into the old furnace slot. Just reattached the propane hose and wires and it started working perfectly. It's a tight fit and takes some time to install - but well worth it. The problem with my existing furnace was a sticky sail switch. I know I could have saved some money by replacing that switch, but the furnace was 13 years old and I didn't want future problems so went with this new one.
Review: I am thrilled to death… - I can say my unit arrived in perfect shape. I don’t mind the plastic fan noted in other comments. If it is ever an issue I will just use the metal one from my old unit. The instructions are good but not nesssesary after you read once. It’s a very easy install and this is my first time doing any work like this. Don’t be afraid. Save money and do this yourself. It works as soon as installed with no fuss. I can’t say it is the most quiet heater I have heard but is definitely not worse or as bad as some. I will report next year but I believe this is a great quality replacement and would definitely recommend this to even a beginner like myself.

### ⭐⭐⭐⭐⭐ Very pleased with this furnace core.
*by B***N on November 29, 2025*

I received this unit yesterday, installed it today. It was a perfect swap. Easy to install. On my motorhome you must take the whole furnace box out as the old unit and new unit slide out from the back. Once the new furnace was in, turned on the thremostate and it lit right off. It is much quieter that my old one. The furnace core comes with the circuit board. And sail switch installed. So far, very happy.
