Friedrich MW18Y3FM Air Pressure Switch
The primary function of the switch is to determine whether the main blower is circulating the air as it should. The majority of pressure switches have a manual reset feature, from which the switch will have to be manually reset or the entire system will not run. This is part of a small, but important collection of safety creations designed to keep you safe.
Symptoms to Look for when the System Pressure Switch is Starting to Go
- Inaccurate voltage range being read.
- Your heating and cooling system will not function properly.
- The set temperature in the house is hardly ever fully attained.
