How to Troubleshoot Central AC Electric Control Relay Problems
Central air conditioning (AC) electric control relays are vital components of any air conditioner, allowing the AC system to regulate and monitor the flow of electricity. When these relays malfunction or break down, the AC system cannot function properly, leading to costly and often dangerous problems. With an understanding of the components and processes involved in central AC electric control relay repairs, homeowners can troubleshoot and determine the best course of action for fixing the problem.
Types of AC Electric Control Relays
Electric control relays work in AC systems by sensing voltage and temperature, creating an electrical path and opening and closing electrical contacts. They are typically found in the outdoor compressor, outdoor fan motor, and evaporator coil. The most common types of AC control relays are solid-state, frequency, and fixed-current relays.
-
Solid-state relays (SSR) – These lightweight, solid-state components, also known as electronic switches, produce a low electrical current and work through the use of low-voltage commands to control device operations.
-
Frequency relays – These are sensitive components that sense and monitor frequency levels to control the speed of fan and compressor motors.
-
Fixed-current relays – These relays, often incorrectly referred to as “fuse relays”, control the current flow sent to the AC system components.
Troubleshooting AC Electric Control Relays
When a central AC electric control relay malfunctions or breaks down, it can cause a wide range of problems including compressor failure, reduced air flow due to a failing fan motor, and freezing in the evaporator coil. Common indicators of electric control relay malfunction include frequent tripping of the air conditioning circuit breaker, clicking noises coming from the electrical box, and an AC system that fails to turn on.
-
Tripped Circuit Breaker – When the circuit breaker that powers the AC system trips multiple times, this could be an indication of a malfunctioning relay.
-
Clicking Sound – If the AC system produces a clicking sound, this means that the relay is likely switching on and off ineffectively.
-
System Failure – If the AC system is failing to turn on, this indicates an issue with the electric control relay.
Replacing AC Electric Control Relay
Homeowners can be hesitant to replace their own electric control relays, but as long as safety precautions are observed, it is generally a straightforward process. The relay should be located in the control box and is typically held in place by two screws. The electrical contacts of the relay should be inspected for corrosion or other damage before being tested for continuity. If the contacts are damaged, the relay needs to be replaced with the same model.
If the contacts of the electric control relay are in good condition, the relay itself should be tested to determine if it is functioning up to par. A digital multimeter can be used to test the resistance of the relay, though it is recommended that homeowners call a professional if they aren’t comfortable handling this issue.
In some cases, replacing the electric control relay may fix the issue, but more often than not, the entire AC system will need to be inspected and repaired to ensure proper functioning. For this, it is generally advised that homeowners contact a reputable and reliable HVAC contractor to thoroughly inspect the entire AC system and provide a reliable solution.
