If A Condenser's Contactor Could Talk

If the indoor air handler (blower) is running, but the outdoor (condenser) unit isn't, the contactor will give you telltale signs of what could be wrong with the system and what to troubleshoot next. Closed contacts are a sign of a high-voltage problem. Open contacts indicate a low-voltage problem. On a closed contactor, check the lead terminals to see if there is proper voltage to the contactor (220v-240v). If the voltage is correct, check the other side (load terminals) of the contactor. You should have the same voltage reading. If the voltage is not the same, the contacts are not allowing the electric current to flow through them. Check for worn, blocked or defective contacts. If you do not have proper voltage readings to the contactor, there is a problem with the electric circuit to the condenser. This could be a tripped or defective circuit breaker, service disconnect fuse, disconnected, or open wire. If you have the correct voltage on both sides of the contactor, there is a high-voltage problem in the condenser. This could be the compressor, fan motor, capacitor, disconnected, or open wire. Note: If you reset a circuit breaker or replace a fuse and it trips/blows again, an experienced technical guess would indicate a problem in the condenser. Open contacts are evidence that the low-voltage control of the system is not closing the contacts. Low-voltage troubleshooting can be difficult because each HVAC manufacturer has different fail-safe devices or sensors that are low-voltage controlled. These components are wired in series and shut down the outdoor unit by opening a low-voltage circuit when a problem occurs in the system. These devices or sensors could be temperature or pressured controlled. Some units have logic circuit boards that process information through sensors before allowing the unit to come on. Note: To avoid electric shock, the voltage to the condenser can be shut off at the service disconnect or circuit breaker to troubleshoot the low-voltage control circuit. The contactor's low-voltage magnetic coil should be the first place to check for a low-voltage reading. This should be 23v-25v at the coil's terminals. If there is no voltage to the contactor's coil, there is an open circuit in the low-voltage control wiring. This could be an array of devices, sensors, or issues. Check the low-voltage wiring diagram and work your way down the ladder. You will find an open circuit in the system that is not sending low-voltage to the contactor. If an air conditioning or heat pump condenser is not working, but the indoor unit is, look at the contactor. It may tell you what you need to know.
