Fan Cycle Switches
HVAC fan cycle switches are crucial to a condenser fans’ performance in HVAC systems, cycling fans on and off as needed to maintain proper head pressure. This is particularly necessary in low ambient temperature conditions where refrigerant can condense in condenser units during cold weather....Read more
Fan cycle switches are also known as condenser fan cycling control. HVAC fan cycle switches are pressure-sensitive, monitoring refrigerant pressure and then activating condenser fans if the pressure exceeds a set amount. By doing this, they help maintain efficient cooling and stabilize refrigerant pressure during varying load conditions. In addition, they help prevent a variety of things: compressor short cycling, overcooling and energy waste, and reduced equipment lifespan.
If the fan cycle switch fails, then condenser fans will not be triggered to turn on or off, leading to either continuous operation or not running at all, affecting the cooling performance of the unit. It can also lead to high head pressure and compressor strain, prompting system shutdowns. It’s best to check on the status of fan cycle switches during seasonal maintenance to ensure you keep energy costs down and extend the lifespan of the condenser fan. Environmental exposure and refrigerant leaks can also affect fan cycle switches, so be sure to inspect them if you’ve recently experienced either of those scenarios.
