Lennox 34W70 Jumper Plug

The Lennox 34W70 Jumper Plug is a basic yet effective part of many Lennox HVAC systems for diagnosing electrical issues. It works more or less as a temporary link between two points in a circuit. This enables technicians to expose certain parts of the circuit or avoid wires that produce wrong signals. By selective amplitude removal techniques, technicians can be able to identify the problem area of electrical problems in HVAC systems. It may be useful to bypass a circuit to find out whether a specific circuit is causing the system to malfunction.
