How to troubleshoot your Westinghouse central air conditioner when it won't start

• Check for electrical power.Check the house circuit breaker for the central air conditioner to make sure it’s turned on. Reset the circuit breaker if it’s tripped.
• Check the condensate drain.Central air conditioners often have a float switch mounted on the evaporator condensate drain pipe that shuts off the air conditioner if condensate water isn't draining. Shut off power to the central air conditioner and check for condensate water backing up in the evaporator drain system. Clear the drain to reset the float switch and restore power to the central air conditioner.
• Check the thermostat. Make sure you have the thermostat set correctly. Adjust thermostat settings if necessary. If the thermostat doesn't have power, check its wiring and reconnect any loose wires. Replace the thermostat if it isn't working.
• Examine the electronic control board. Disconnect electrical power to the central air conditioner and check the electronic control board wiring connections. Reconnect any loose wires and repair any broken wires. Check for burn marks on the circuit board and replace the electronic control board if you see burnt spots or melted wires.
