Hvac Fan Relay Wiring Diagram Wiring Diagram And Schematic Diagram Images 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.”. 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.
Hvac Fan Relay Wiring Diagram With dual cooling fans, there are two methods for wiring up the relay kit. this is based on the draw from the fans, if the fans are larger and draw more than 15 amps each, it's recommended to install a second relay kit as shown below. for smaller fans, both fans can be connected to a single relay as shown above, and the proper fuse should be. 30: constant 12v, unswitched 85: signal (switched 12v) 86: ground (completes circuit) 87: consumer (fan) 12v 87b: extra consumer (same as 87) 12v switched wire. may be green wire at a c clutch. note: or in an ’84 to ‘89 240 you may use the a c power ‘on’ wire: red white wire at ac switch microswitch in dash. This is how to troubleshoot an hvac electrical fan relay! i go over how to read the ratings for time, how to read the resistance, where to connect the 24v, h. 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.

In the case of the 90 340, it is the bottom two terminals of the relay. even though the coil is unmarked on most 90 340 relays, you can find it easily by locating the terminals with the small strands of wire connected. these two points connect through the electromagnetic coil. when 24 volts of potential is applied across the coil, the switch.
