What it is
The Schwank A2750537 is an air pressure switch for Schwank SU22/38 appliances. It monitors the air pressure within the appliance's combustion air path and proves that airflow is present before and during operation. The switch forms part of the appliance's safety interlock chain, allowing the burner sequence to proceed only when the required pressure condition is met.
Before you order
- Confirm the part number A2750537 against the label on the existing switch or the appliance's parts listing.
- Check that the appliance model matches the SU22/38 reference before ordering.
- Inspect the associated sensing tubes and connections for condition, since these affect switch operation.
