What it is
The Potterton 5139794 is a flow and return sensor used on Potterton Commercial IHE series boilers. It monitors the flow and return temperatures of the heating circuit, providing the readings the boiler control needs for firing rate, modulation and safe operation.
Signs this part needs replacing
- Boiler locks out or shuts down with a flow or return temperature related fault
- Temperature readings at the boiler appear inconsistent with actual system conditions
- Heating output becomes erratic, with the boiler failing to modulate as expected
- Intermittent faults that clear on reset but return once the boiler is running
Before you order
- Confirm the appliance is a Potterton Commercial IHE 100/300 or IHE 150/300
- Check the existing sensor and its lead for part number 5139794
- Inspect the electrical connection and wiring harness for damage before fitting a new sensor
- Isolate the power and water supply as required before removing the sensor
