Raypak 600893B High Limit Switch Replacement 140°F Auto Reset
If the heater is shutting down on temperature safety and then restarting on its own after cooling, the high limit switch is one of the first protection parts to inspect. A faulty limit can cause nuisance trips, but if it is reacting to a real overheating issue, that root cause still has to be corrected before the heater is considered fixed.
This 140°F auto-reset high limit switch monitors temperature and opens the control circuit if the heater exceeds the specified threshold. Unlike a manual-reset limit, it closes again automatically after the temperature drops back into range. Replacing it restores an important layer of overheat protection in heaters designed for this switch style.
- Heater shuts down on temperature safety and later restarts automatically
- Repeated high-temperature shutdowns occur during operation
- Limit switch has failed or is no longer responding correctly
- Need to fix a Raypak heater with overheat safety control problems
What this part does: It interrupts heater operation at the rated temperature threshold and then resets automatically after cooling.
Compatibility: Used on select Raypak heaters requiring a 140°F auto-reset high limit. Confirm with your model number before ordering.
- Part Number: 600893B
- Type: High limit switch
- Temperature Rating: 140°F
OEM Value: A genuine Raypak safety switch helps maintain the intended protection point and reset style. High-limit replacements are not the place for guesswork because the wrong control can create nuisance shutdowns or compromise safety.
