American Standard Immediate Shutdown After Start

American Standard air conditioner cycles on but shuts off after a few seconds

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

High-pressure trip due to blocked condenser, Faulty compressor, Loose high-voltage connections, Defective control board

Safety first: Turn off power to the outdoor unit before inspection.

Clean condenser coil: Remove debris and rinse the coil thoroughly from inside out.
Inspect fan operation: Ensure the condenser fan starts and runs at full speed. A non-running fan can cause rapid high-pressure shutdown.
Check electrical connections: With power off, tighten all lugs on the contactor and terminal block.
Professional service: If the unit still shuts down quickly, a technician should check pressures, compressor current, and control board operation.
