My ADP SEP propane heater control board developed an electrical fault and failed spectacularly in a ball of flames. This replacement conversion board worked perfectly after installation and was simple to follow the instructions. You do need to mount the board on a mounting plate(provided) and clip a wire. The required conversion harness is included for different models of furnace(I required a 6-to-9 pin) to allow this new board to work. It should be about a 20 minute job.

I have no issue with Plumbers Stock, per se. I received my order long before the website ever showed it as being shipped. Not necessarily a bad thing, I guess, and being the patient soul that I am, along with with the heating season still six (6) weeks away, I thought "I can wait." I came home one day and there it was on my front porch. The website still showed the shipping as "pending." I may take issue with ADP though. I encountered two (2) issues in the upgrade installation process. Number one, the directions never mention to remove the old control board mounting panel. Just to remove the old control board. I wasted a lot of time trying to get the new mounting plate to line up with the old one, but I figured it out on my own. The old mounting plate has to be removed and discarded. The second issue was the directions read to hook up the "BLACK" wire on the 15-pin to 9-pin adapter harness to the "Combustion Blower" terminal on the new board, but there was no black wire. Every color but. I finished the upgrade, and a gray wire was the only wire left over, so I followed the gray wire back through the harness, found that it did go to the combustion blower so I hooked it up to that terminal. Then, I applied power, set the thermostat to call for heat, and the unit started up without incident. Here is my "Caveat Emptor." (Latin for "Let the Buyer Beware.") I strongly recommend that if you don't have an HVAC or electrical background, please don't do this upgrade yourself, because you may let the smoke out of the new control board, and if you do, you'll be out $178.00. I have both, an HVAC and electrical background, so I was able to do this myself, but with some difficulty. The difficulty being big hands working in a small space. My 26 year old unit heater is working properly now. Should be good for another 26 years! Thank you, Plumbers Stock, for having this part in your inventory. You saved me over $550.00! This is my second purchase from Plumber's Stock and they seem to have the parts for older equipment, often times in stock. I'll be back, because they are now my first choice when I need parts and equipment like this. Cheers everyone! Jeff Gardner Lonsdale, Minnesota

I followed the installation instructions and the unit has been performing flawlessly for the last three months.

Control Board worked as it should. Kit was complete, and instructions reasonably straightforward. Would but from PlumbersStock again.

This board solved a months long intermittent problem I was having with my ADP heater. Such a relief!
