Lochinvar & A.O. Smith 100170648 Sensor
The Lochinvar & A.O. Smith 100170648 Sensor is a critical OEM replacement part designed for precise water temperature control in commercial and residential pool heaters. Engineered to provide real-time resistance data to the integrated control board, this thermistor-style sensor ensures the heating system maintains accurate set points to optimize energy efficiency and equipment longevity. For technicians troubleshooting E07 probe faults or intermittent cycling, replacing a drifted or scaled sensor is a standard preventative maintenance step. This high-accuracy pool heater temperature sensor is compatible with various Lochinvar EnergyRite models and specific A.O. Smith heating systems, featuring a robust housing built to withstand the corrosive environment of chemical-treated pool water. When field-testing, verify resistance values against manufacturer-specified temperature-to-ohm tables to ensure proper thermal sensing performance.
Key Benefits
- Precision Thermal Regulation: Direct OEM 100170648 replacement provides accurate feedback to prevent overheating and ensure consistent water temps.
- System Reliability: Resolves common sensor error codes (like E07) that cause premature heater shutdowns or failure to ignite.
- Rugged Construction: Designed with specialized materials to resist scale buildup and chemical degradation in harsh circulation loops.
- Simplified Field Replacement: Compact form factor and standard connector design allow for rapid installation during service calls.
Common Questions
How do I troubleshoot a suspected sensor failure?
Use a multimeter to measure the sensor resistance at the control board harness. Compare your reading to the manufacturer’s resistance chart. If the ohms are significantly out of range for the current water temperature, the sensor has drifted and requires replacement.
Will this sensor fix an E07 error code on my Lochinvar heater?
In most cases, yes. An E07 Probe Fault typically indicates a shorted or open sensor. After verifying that the wiring harness is intact, installing a new 100170648 sensor usually clears the fault.
Does this part work with both inlet and outlet orientations?
While this is a primary pool heater sensor, you should always consult your specific unit's wiring diagram and parts list to confirm if your model requires distinct sensors for the inlet and outlet (hi-limit) positions.
