The Goodman 10135604 is a genuine OEM control relay built for the ASZ130301AB heat pump. This relay handles the low-voltage-to-line-voltage switching that energizes key loads in the condensing unit, allowing the control board or thermostat signal to safely make and break higher-current circuits. A worn or chattering relay is a common cause of intermittent no-cool / no-heat calls, so a fresh OEM relay restores dependable switching.
The 10135604 is factory-matched to the ASZ130301AB coil voltage, contact rating, and terminal layout. Generic "universal" relays may carry a different coil resistance or contact current rating, leading to nuisance dropouts or contact welding. Installing the OEM relay ensures correct electrical characteristics and preserves warranty coverage.
Difficulty: Moderate. With power disconnected at the breaker, the relay unplugs/unclips from its terminals and the replacement snaps into place — typically 20–30 minutes. Always photograph the wiring before removal and confirm power is off with a meter. A qualified technician is recommended if you are not comfortable working around line-voltage terminals.
Genuine Goodman reliability. Order the 10135604 to restore clean switching to your ASZ130301AB heat pump.
