Nordyne M3RL-060A-BW Air Pressure Switch
The function of this type of switch is to sense whether the primary blower is blowing air. The vast majority of pressure switches made today may have a manual reset, which makes you reset it by hand or else the system will cease to function. This is one of the critical mechanisms designed to keep you from harm.
Signs to Look for when your Air Pressure Switch is in Need of Replacement
- The correct temp seldom fully attained.
- Bad voltage range running through the switch.
- Furnace will not operate at all.
