In this HVAC Training Video, I Show How the Fan Switching Relay Works and How to Troubleshoot the Coil and Switching Terminal Contacts.
Start by turning off the power to the HVAC system and removing the relay from its socket. Then, use the multimeter to test the continuity across the relay’s terminals. If the multimeter indicates an open circuit, it means that the relay is faulty and needs to be replaced.
Follow a step-by-step troubleshooting process to isolate and resolve relay issues, ensuring your HVAC system resumes normal function with minimal downtime. Learn how to repair or replace faulty relays effectively, and consider seeking professional assistance if the task is beyond your skill level.
Learn how to wire an air conditioner relay with a comprehensive diagram. Ensure proper installation and functionality of your AC system.
Learn how to wire a fan relay in an HVAC system with the help of a wiring diagram. Understand the different components and connections involved in the wiring process.
The purpose of the relay is to allow line voltage equipment to be controlled by a 24V thermostat circuit. You can turn on or off as many pieces of equipment as you have switches on the relay. Testing a relay. Since there are two parts of a relay, you need to troubleshoot both.
18 Νοε 2022 · The start capacitor is REMOVED from the circuit by a relay called the potential relay. The potential relay is normally closed, and it OPENS when a sufficient PICKUP voltage is present between the 5 and 2 terminals on the relay.
