The Goodman 0130M00014 is a genuine OEM 240-volt relay used in Goodman WPC4342AHAB air conditioning systems. The relay uses a low-power control signal to switch a higher-voltage load — energizing components such as the blower, heater, or auxiliary circuits on command from the control board. When a relay's contacts pit, weld, or fail to close, the controlled component won't run reliably (or won't shut off), causing intermittent operation, no-cool/no-heat calls, or short cycling. Installing the correct OEM relay restores dependable switching.
The genuine Goodman relay is rated for the exact coil voltage, contact configuration, and load current your system was engineered around. Generic relays may have mismatched coil voltage or lower contact ratings, leading to premature failure or unsafe operation. OEM ensures correct pinout and reliable, code-compliant switching.
Moderate — Requires disconnecting power, photographing/labeling wiring, and swapping spade or screw terminals. Straightforward for a confident DIYer; always verify power is off before servicing.
