Should contacts on pressure switch be open or closed?
There are two main types of pressure switches: normally open (NO) and normally closed (NC). These terms describe how the electrical contacts within the switch behave. In a normally open switch, the contacts remain open when the pressure is within the desired range. However, when the pressure exceeds this range, the contacts close to trigger a response. On the other hand, in a normally closed switch, the contacts are closed when the pressure is within the acceptable range. They only open when the pressure goes beyond the specified limits.
Why is my pressure switch staying on?
If the air intake or exhaust of your furnace is blocked with debris, it can cause the pressure switch to stay open. This happens because the blockage prevents the inducer fan from creating the necessary negative pressure. As a result, many homeowners often encounter the issue of a furnace pressure switch getting stuck in the open position.
How do I know if my pressure switch is bad?
Signs of a faulty well pressure switch can be easily identified. When the pressure in the tank exceeds the designated cut-off pressure, the pump fails to shut off. Similarly, when the tank’s pressure falls below the predetermined cut-on pressure, the pump doesn’t activate. These symptoms clearly indicate a malfunctioning well pressure switch.
Why would a pressure switch not shut off?
Your pump may run continuously if there is a problem with the pressure control switch. This can be caused by clogged tubing or burned contact points. Another possible reason for continuous running is if someone has adjusted the cut-out pressure to a level that exceeds the pump’s capacity.
