A Misc Hardware K71-36 Potential Relay Kit controls compressor startup timing to support smooth cycling within the HVAC setup.
The potential relay kit controls the compressor start circuit by engaging and disconnecting the start components at the proper time, allowing the heating and cooling unit to start efficiently and run reliably. Its design matters because the relay must respond accurately to electrical conditions and withstand repeated cycling to protect the compressor from hard starts, overheating and unnecessary strain.
The potential relay kit may be failing if the HVAC system has trouble starting, the compressor short cycles or the unit runs inconsistently during operation. You might notice physical signs such as burning odors, discoloration or damaged terminals and environmental signs may include repeated overheating or performance issues during high-demand conditions.
