My AC clicks but the compressor does not turn on. What is wrong?

Clicking from the outdoor unit without the compressor starting usually means a worn contactor. The contactor is the relay that sends power to the compressor.

Overview

This OEM 24VAC relay (part number L01H009, OEM ref AG90-23242-024W) is a low-voltage switching relay used in the control circuit of the ICP/Heil/Tempstar SUP20M2301CIA package unit. A 24-volt coil energizes the relay contacts to switch a load — a fan, heater, or auxiliary circuit — on command from the control board or thermostat. When the relay fails, the controlled load stops responding: a fan that won't start, a stage that won't energize, or intermittent operation as worn contacts arc. Relays fail from contact pitting, a burned-open coil, or vibration over years of cycling.

My AC clicks but the compressor won’t turn on. What’s wrong?

Clicking from the outdoor unit without the compressor starting = worn contactor. The contactor sends power to the compressor. When its contacts are pitted, it clicks but can’t make solid contact. Look for: visible pitting/burn marks on the contactor face, intermittent operation, or buzzing.

Is this contactor compatible with Bryant or Payne too?

Many ICP parts are cross-compatible with Bryant and Payne since all three brands are manufactured by Carrier Global Corporation. The same physical part is often used across brand labels with different model numbers. To verify: check your Bryant or Payne equipment service manual for cross-compatible part numbers, or email info@nationalhvacparts.com with your model number.

Should I use OEM or aftermarket for my ICP contactor?

OEM recommended for reliability and warranty compatibility. OEM parts match exact factory specifications for proper fit, performance, and safety. While aftermarket alternatives cost less upfront, the risk of improper fit and reduced lifespan usually makes OEM the better value long-term.
