Raypak 010354F Blower Pressure Switch for R337A Heaters
If your R337A heater starts the ignition sequence but shuts down before lighting, or the blower runs without proving airflow correctly, the blower pressure switch is one of the first components to inspect. A failed switch can leave the heater locked out because the control never gets the draft proof it needs to continue.
This blower pressure switch monitors pressure in the induced-draft system on compatible R337A heaters. It confirms that the blower is creating the correct operating condition before ignition can proceed. When the switch fails, sticks, or reads incorrectly, the heater may never move past pre-ignition safety checks.
- Blower runs but heater will not proceed to ignition
- Pressure proving fault stops startup sequence
- Intermittent lockout tied to draft verification problems
- Need to fix a Raypak heater with confirmed blower pressure switch failure
What this part does: It verifies blower-generated pressure so the heater can safely continue through the ignition sequence.
Compatibility: Designed for Raypak R337A heaters. Confirm with your model number before ordering.
- Part Number: 010354F

OEM Value: A genuine Raypak pressure switch helps maintain the intended draft-proving threshold and connector fit. Safety switches like this are not the place for guesswork because the wrong switch can create lockouts or unsafe operation.
