Good Afternoon,
I have a Carrier Weathermaker 8000 that has a heating issue. I had a technician look at it and after much testing he handed me the bad part. It was a Tridelta pressure switch. I purchased it and have installed it myself as there wasn't much too the part. Now, the problem is that the technician did not reattach a white wire(neutral) to the control board. This white wire is coming directly out of the electrical box inside the cabinet and it seems to go to a tab on the control board marked L2. The control board is a replacement to the original and it is labeled ICM 282. I have already hooked up the wire and plugged in the unit. I see there is a solid red LED light on the control board, but heard a hum coming from the unit, so I unplugged it.
Can anybody confirm that the L2 tab is the correct tab, or suggest the correct tab?
Thank you in advance.

L2 is correct,

L1 or line 1 is Hot and L2 is neutral. Black is always Hot and White neutral.

The humming is normal and is the transformer. The Red LED is a good sign and means the power is on.

No worries.

Hi Carmon,
The technician had to order the part and it would take a week to come in. He said it would $350.00 to install it. I purchased one on ebay for 11.00. It only had two wires and one hose to connect, it looked like an easy repair to do myself.
Thanks
