Hvac Safety Switch Location

A float switch is essentaially an electronic water sensor for your hvac system.

Hvac safety switch location. 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. Tell us about it in the comments below. Water dripping through the ceiling and an air handler sitting in a drain pan full of water directly above it is more common than you think says christian smith an hvac contractor. How the furnace switch works.

One on the low pressure side before the ac compressor and one on the high pressure side. However small lizards or frogs occasionally become lodged in the pipe stopping the flow of the water. The ac pressure switch іѕ a ѕаfеtу ѕwіtсh thаt monitors the рrеѕѕurе оf thе refrigerant on the high and low pressure sides on your air conditioning system. 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. Central air conditioning systems have an outside unit with a compressor that runs and provides the cool air that runs through the vent system. So you do often have two different ac refrigerant pressure switches on your car. The reason your air conditioner won t turn on could be because the condensate drain line is clogged.

Do not bypass the safety switch or you could have a huge water mess in your home. 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. Reduce or prevent water damage. Prevent dangerous mold growth.

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. As any homeowner knows areas that collect moisture are susceptible to mold. This switch could be the problem. 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.

If these items do not solve your problem call an hvac service professional to help. Air conditioning float switch and safety switch explained. When ac units run they create condensation which is removed from the unit through a drain line. Most of the time an algae growth is the culprit blocking the drain.

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.
