What causes Honeywell Security Sensor pump to not operate?
- HHailey HuntSep 12, 2025
If the pump on your Honeywell Security Sensor is not operating, it could be due to: * The diffusion cap is off or not attached correctly. Attach the diffusion cap and ensure the seal is tight. * There is a blockage in the tubing. Clear the blockage. * The particulate and/or moisture filter requires replacement. Replace the filter(s).
