Description
The Tecumseh K71-37 Relay Kit is a genuine OEM-quality replacement component designed to restore proper starting and operational performance to Tecumseh refrigeration compressors. Relay kits are a critical part of the compressor electrical system, ensuring the start winding is correctly energized during startup and then dropped out of the circuit once the compressor reaches running speed — protecting the motor from overheating and premature failure.

Why Replace the Relay?
A faulty relay is one of the most common causes of compressor hard-start or no-start conditions. Replacing a worn or failed relay with a properly matched kit like the Tecumseh K71-37 is a cost-effective first step in compressor diagnostics and repair, often eliminating the need for a full compressor replacement.
