Common Questions & Answers

What is the difference between a 1-pole and 2-pole relay in HVAC?
A 2-pole relay like the P283-0340 can switch two independent circuits or both legs of a 240V circuit simultaneously, whereas a 1-pole relay only switches a single line.

Can I use the P283-0340 if my old relay is an F87110340?
Yes. This unit is the official Carrier OEM replacement for the F87110340 and 1056363, ensuring the pin mapping and electrical ratings match exactly.

Why is my blower motor not turning on even with 24V at the thermostat?
If the 24-volt control coil receives power but the contacts fail to close, the internal switching mechanism may be compromised. Replacing the relay is the standard technical resolution.
