Control Board

was a great replacement on time as usual

Supply House is my go to for all my mechanical needs. The customer service is very knowledgeable and parts are very reasonably priced. The one and only place I go to!

Blower motor stopped working and we diagnosed it to be the board voltage output at 0V. Called Trane and they said my board (CNT07941) was obsolete and I would need to buy their retrofit kit at around $500 just for parts, and would need to replace burners and harnesses to use this new control board. Did some Googlin' and found these guys, read the positive reviews, and took a stab at it for a 3rd of the part cost and a lot less labor involved... Worked like a charm. May not have been the same PCB manufacturer, but the CNT# was the same, the board layout was the same, and their description was spot on accurate. I sent the website to my furnace guy and told him to save this for future jobs when the OEM tells him they don't have it anymore!

Customer service is excellent helping me find the right part!

Fast shipping. Thank you very much!

Perfect replacement control board for my furnace. Wiring was easy enough. Everything works smoothly.

21-year old Trane XB80 furnace. Symptom - heat would come on, after a while gas in the furnace would cut off but blower fan kept running non stop. Thermostat would show 'Heat On' but only cold air from the vents. Swapped our thermostat, limit switch and flame sensor but same problem. Got this board to replace the original White Roger unit (CNT2789) and all is well again.

The board install went smoothly transferring on wire at a time and when powered up the unit fired right up 🔥 This is my second order with them and I've gotten consistent great customer service and quality parts. 🥇

Original part number was no longer available. Friendly online support person assisted by cross-referencing the OEM part number with the upgraded part number.
