Defrost Timer Board, Fits Brand Carrier

I have had this installed for about two years now with only one issue, and I found a fairly simple work around for it. The temperature sensor on the outside coils on my unit worked backwards from what is programmed on this card. When this board checks for defrost mode it checks on the temperature sensor and if it is in the "open" position it will go into defrost mode. My sensor goes into "closed" position when it is time for defrost (I could have this completely backwards, it has been a while since I have had to tinker with it). My solution was to cut thee wires to the sensor and jumper it out so that every 90 minutes now it goes into defrost whether it needs it or not. This has to be reversed for the summer months or the unit will not function properly. I have been intending to purchase a sensor that works with this board but.. ah hell, you know how it goes. If it aint broke dont worry about it!

Shipping was very fast, exact replacement for damaged timer PCB. I would highly recommend this company

This was exactly as described and after I installed this to replace the burned board and I replaced my contact while I was in and it fired right up! Very pleased with the part. It was identical. Same markings etc.

Be aware that there are 2 styles of this board so when you order be sure to verify what kind of wire connections your original board has. Mine had spade clips and I purchased the incorrect one the first time. Was exchanged with no issues!

Fit my Heil HVAC unit with no issues.

Works great. The wiring was a breeze. Take a picture of the board before removing it to help with the wiring in case you forget where to plug one in. I removed one wire at a time from the old board and put on the new board to eliminate confusion

5 stars still going after 3 years

Not working product bad
