True or false: A loose wire connection can cause lower than normal amperage in an HVAC system.

A loose wire connection can indeed cause issues within an HVAC system, but the impact on amperage is a critical factor to understand.

When a wire connection is loose, it can lead to increased resistance in the circuit. This increased resistance does not typically lead to lower amperage; instead, it usually results in higher resistance along with poor conductivity. In most cases, this can create heat and possibly lead to circuit failure or further malfunctioning of the system as the components may not receive adequate electrical power.

Normal operation relies on solid connections to ensure that the required current flows through the components efficiently. If a connection is loose, there can be a drop in voltage, which influences how the system operates.

In sum, the premise that a loose wire connection could lower the amperage is misleading. It primarily affects the functionality through resistance and heat, rather than continuing to allow normal operation at reduced amperage.
