Resideo 120320 Cell Assembly
The Resideo 120320 Cell Assembly is the critical sensing component for C554A and C6031A cadmium sulfide flame detectors, designed specifically for commercial and residential oil-fired burners. This replacement cad cell features a sensitivity range of 400-1600 Ohms at 2 foot-candles, ensuring precise flame intermittent detection and reliable signal transmission to the primary oil safety control. The 120320 is functionally identical to the 120320/U, providing a direct drop-in solution for servicing honeywell flame sensors. Field technicians should note the importance of maintaining an airtight seal within the burner housing to prevent ambient light interference from tripping the flame detection system. This assembly includes the lead wires and cell bracket, allowing for a streamlined installation during routine HVAC burner maintenance.
Key Benefits- Universal Compatibility: Direct replacement for all standard C554A assemblies and 120320/U models.
- High Sensitivity: Accurate 400-1600 Ohm resistance range provides stable flame monitoring.
- Lead Wire Integration: Pre-attached leads simplify the connection to the primary controller.
- Industrial Reliability: Robust construction withstands high temperatures within the burner compartment.
Is the Resideo 120320 different from the 120320/U?
No, these parts are technically identical. The "/U" suffix simply denotes universal retail packaging, but the internal cell specifications and performance are the same.
What causes high resistance readings on a cad cell?
High resistance is typically caused by soot buildup on the cell face, a misaligned burner, or an aged photocell that has lost sensitivity and requires replacement.
Does this cell work with all oil primary controls?
The 120320 is designed to work with any control system calibrated for a standard cadmium sulfide flame sensor, including the R8184 and R7284 series.
