Pressure Switch .90, 11U72

Got it installed just before a big winter storm. Worked great. Tip: in addition to part # which changes for older HVAC units, also verify the pressure setting matches the original.The location of the pressure tube ports moved but the mounting bracket snapped in exactly as old one and it does the job.

Easy to install, great price, fast delivery.

Shipped quickly and was the exact replacement.

So, On a Saturday Morning My Son calls me in California from Delaware. There is no Heat in the House. And it's Freezing outside. No Snow but it's expected soon. Using the Camera on His and His Wife's phone, we go thru the wiring diagram and test with the VOM meter he finally got a few months back. ( Ain't technology great?! ) Fans on, Glow Bar on, Runs a minute, Shuts off. Testing lead to power at the air flow switch, but not out of it. Jumped the switch,and the heater stayed on. Good for a diagnoses. More camera and screwdriver work, the switch came out, and we found a number on the switch. But when I plugged the number into the SupplyHouse Search, a couple possibilities came up. None of them Anywhere Close to Exact Matches.. As I was reading, and trying to determine which unit I needed, the Chat Box popped up. On a Saturday ! Gave him the numbers I had, and in a few minutes he came back with the correct part number I needed. He then went on to assist me in getting the part shipped to my Son's address, and charged to My account. Tuesday My Son called, and told me he had heat in the house, and snow outside! I Thank You ! My Son Thanks You ! His Pregnant Wife Thank You ! My unborn Grandson would Thank You as well, but He was nice and warm ! Above and Beyond Service!
