Easy to make install. However, mounting may need to be customized.

I’m an electrician and my gas furnace stopped working just as the temperature dropped. The led light on the circuit board was flashing 3 times which meant the pressure switch was still open. (FYI : the blower motor is supposed to come on which creates negative pressure which pulls the pressure switch closed so the gas burner can fire up safely).I verified that the pressure switch was bad, then called around to different HVAC stores for a replacement. They are not allowed to sell to the general public because of safety regulations.Fortunately I found a replacement on Amazon!Make sure you have the proper pressure switch (voltage, pressure, model number) and turn off the gas and power at the furnace before working on it. There are videos you can watch to make sure you do it safely and correctly.

Not what they show in the pictures. Not the right part. Very disappointed.

Worked well as a fix to a problem diagnosed by the HVAC company.
