Air Handler Fan Relay Wiring Diagram Wiring Diagram Basic air handler wiring for beginners. learn wiring and schematic reading necessary for beginners to develop solid diagnostic skills.help me out. follow me. Again, ensure a secure connection to prevent any loose wires. if you are using a fan center relay, you will need to connect the high voltage wires as well. locate the terminals labeled “line” and “load” on the relay strip. connect the incoming power wires to the “line” terminals, typically labeled as “l1” and “l2.”.
Air Handler Fan Relay Wiring Diagram Step 4: connect the power supply. start by connecting the power supply wires to the air handler. this typically involves connecting the black wire to the live (hot) terminal, the white wire to the neutral terminal, and the green or bare copper wire to the ground terminal. step 5: wire the thermostat. Explaining how to wire up a fan relay on fur down style air handler. In this hvac training video, i show how the fan switching relay works and how to troubleshoot the coil and switching terminal contacts. i take the relay apar. The hvac fan relay, crucial for furnace, air conditioning, and ventilation, is a critical component that often goes unnoticed until your comfort is compromised by heat or cold. this small but mighty part plays a pivotal role in regulating electricity flow, ensuring that your heating and cooling systems kick into action precisely when you need.

Step 3: connect the wires to the relay terminals. connect the wire from the control signal (thermostat or control board) to the coil terminal of the relay. this wire will send the control signal to the relay when a temperature change is detected, activating or deactivating the hvac system. Page 5 voltage pcb block wiring fuse time delay fuse lr40061 fan relay a97020 fig. 3a—fan coil printed circuit board 3. check field power leads l1 and l2. if these are not receiving 2. check sequencer relay number 1 and plug wiring. yellow power, system cannot function. wire should be connected to pin number 9 of plug and to limit switch.
