If your Raypak heater shuts down shortly after startup or displays overheat conditions, the high limit switch may be tripping incorrectly or failing altogether. This safety component is critical for preventing dangerous temperature spikes.
The high limit switch monitors water temperature and shuts the heater down if it exceeds safe limits. A faulty switch can either trip too early, causing nuisance shutdowns, or fail to trip at all, risking overheating. Replacing it restores proper safety control.
