York Defrost Board temp sensors (Heat Pump model number?)

[miki425]

Hello,

Here is a long shot, but someone might have background.

From the picture below, can someone provide an approx model number of this York Heat Pump? Installed in the mid '80's, the sticker on the outside has faded and I have no clue to the approximate model number.

What I do know is that the inside air handler unit is a York model number - N2AHD14A06A, Serial No. MKRS341553. I've been trying to google cross-reference non-stop but no luck.

What I am trying to do is shop for the outside temperature sensors that would connect up to the defrost board. From the schematic it shows 3 sensors: "Ambient/Outdoor Sensor-31degree", "Discharge Senor-21degree", and Liquid Sensor-11degree". So I suspect that the sensors during that time frame would likely be the same across models. *my best guess*. I ordered the defrost board and it will come tomrrow, but wanted to start shoping around for the temp sensor in case it too has failed, based on the suggestion of others here.

Perhaps there is a generic or an after market temperature sensor I could use instead? If, so, please suggest make/model? Which sensor should I be focusing on?

Thanks in advance.

That is a 24 yr old heat pump, anything you do and any $ you spend trying to keep it running is a waste. Its really time to start thinking about replacement, sorry.
