How the furnace switch works.
Hvac safety switch location.
Most people know that air conditioning units cool indoor spaces by removing heat from the air but what many people don t realize is that in this process air conditioners also act as a dehumidifier and remove moisture from the air.
This switch could be the problem.
When ac units run they create condensation which is removed from the unit through a drain line.
A float switch is essentaially an electronic water sensor for your hvac system.
One on the low pressure side before the ac compressor and one on the high pressure side.
Prevent dangerous mold growth.
So you do often have two different ac refrigerant pressure switches on your car.
Have you figured out an a c problem without calling an hvac service.
This safety switch will turn off the compressor which as you learned above is in charge of the ac unit s condensation process by installing an ac wet switch float switch you re avoiding what could be a disastrous event.
The float switch a safety device that shuts the system down when condensation overflows into the drain pan can fail for a number of reasons according to smith.
Reduce or prevent water damage.
If these items do not solve your problem call an hvac service professional to help.
According to building codes a furnace must be supplied by a dedicated circuit meaning the circuit cannot supply power to anything other than the furnace.
What it does it gives your ac system the ability to detect if it has a clogged drain and if the switch detects a clogged drain scenario it immediately shuts the system off.
Most of the time an algae growth is the culprit blocking the drain.
However small lizards or frogs occasionally become lodged in the pipe stopping the flow of the water.
When the drain line becomes clogged a safety switch trips and shuts down your air conditioner.
The reason your air conditioner won t turn on could be because the condensate drain line is clogged.
If the air handler s float switch has tripped the primary condensate drain has stopped up due to a blockage and the blocked water has tripped the float on the float switch.
This circuit is served by its own circuit breaker in the breaker box properly called the main service panel the circuit wiring runs from the service panel to the disconnect switch and from there to the furnace.
Air conditioning float switch and safety switch explained.
Do not bypass the safety switch or you could have a huge water mess in your home.
Central air conditioning systems have an outside unit with a compressor that runs and provides the cool air that runs through the vent system.
As any homeowner knows areas that collect moisture are susceptible to mold.
