Excellent product. Installed easily and fixed my 15 year old furnace.

Worked as advertised and was a plug and play for the Lennox system. Installed in less than 30 minutes and was up and running. Great alternative to OEM high dollar option.

Works great.

Perfect replacement for old unit.

Replaced the the controller on a 13 year old Lennox G40UH with this one.<br />The footprint of this unit was slightly larger than the original so had to drill new holes in the sheet metal for the mounting screws; no problem. Wiring connections are essentially one to one with the original unit. Still, you should be comfortable with wiring to do this.<br />After it was all back together, turned it on and worked right away.<br />That was 3 1/2 years ago and the furnace and AC have been fine since. Yesterday I realized that the furnace was not working ... figures that would happen on the first below freezing night of the year! The diagnostic LED on this board was flashing 3 times indicating &#34;Pressure switch stuck open&#34;. Disconnected the pressure switch tube and cleared it, also cleared the connector nipple on the furnace. Reassembled and now the furnace is functioning again.

Replaced my fried computer and it all worked as it should. The HVAC crooks quoted me $600 for this component. Reported them to the BBB and D&B and left negative feedback on every listing on the internet. Do it yourself, you'll safe a fortune.

Our Lennox AC blower quit working. I did some further tests and bypassed the blower motor and it worked so I knew it was the control board. This White Rodgers control board works seamlessly. It pretty much is plug and play. I suggest just removing the circuit board from the plastic housing and fits like a glove . Shut off AC breaker, unplug 120 plug in attic leading to unit, wear a static wrist band for good measure and just unplug each wire and insert on new board in same location. Easy peezy. Works like a charge with a decent price.

Easy to change. Swapped it myself and saved $400 plus. Don't forget the jumper cable though (included). Without installing this, mine didn't work perfectly until the jumper cable was added.
