Types of Pressure Switches for Ovens

Oven pressure switches have slightly different designs in different types of ovens. In a conventional single-stage oven, there is a pressure switch and it has a hose that leads to the body of the induction fan.

A single stage condensing oven has a pressure switch with two hoses in the switch, one to detect the pressure in the draft inductor / burner cabinet and the other to detect the proper ventilation pressure in the condensate collector box.

Two-stage ovens can have two pressure switches and modulation ovens can have three pressure switches.

A pressure switch that does not turn on can be caused by several problems, including:

• Traction inductor failure

• Air intake restricted

• Strictly combustion air vent

• Leaks around assemblies

• Drained condensate drain

• Pressure switch electrical failure
