Hvac Fan Relay Troubleshooting Replacement Guide In this hvacr training video, i go over how the potential relay works and how to troubleshoot it! i show the wiring and contacts at 5, 2, and 1. If a potential relay is malfunctioning, the compressor motor is in danger of not starting, stalling, locking rotor, or even burning out. that is why technicians should understand how to troubleshoot potential relays.
Troubleshooting The Hvac Potential Relay Youtube Relay When asked about the idea of electrical troubleshooting mistakes being made between 7:30 and 8:20 in the morning, some said that they too had doubts about what they heard on their first day in class. Testing an hvac relay with a multimeter is straightforward. begin by turning off power to the unit, then set your multimeter to the resistance setting. place the leads on the relay terminals; a reading near zero indicates a functioning relay, while infinite resistance suggests a fault. In this hvacr training video, i go over how the potential relay works and how to troobleshoot it! i show the wiring and contacts at 5, 2, and 1. i explain how it controls the start capacitor after the compressor starts. i show the coil and how to measure resistance values for diagnosing the coil or contactor tabs while using a mutlimeter. Mount the relay properly; there is a proper up configuration on most potential relays. use hard starts with real potential relays, not timers, solid state, or other relay types (in my experience). size the relay and capacitor according to the manufacturer's specs.

Each video explains fundamental concepts and illustrates a step by step approach to learning how to troubleshoot a specific problem. this video program explains how a potential relay works in conjunction with a start capacitor in hvacr compressor start systems. In this hvacr training video, i go over how the potential relay works and how to troubleshoot it! i show the wiring and contacts at 5, 2, and 1. i explain ho. How does a potential relay work? a potential relay is an electrical device used in hvac systems to control the starting and stopping of a motor. it works by sensing the voltage across the motor and switching the start capacitor in and out of the circuit based on the motor’s rotational speed. You should read near 0Ω or very very close. while set to continuity with the beep, you should hear the beep sound indicating the contacts are closed. if you read ol or infinity, that means the nc contacts are not open. they would be stuck open. you would need to replace this potential relay.
