What it is
The Worcester Bosch 8738203396 is an NTC temperature sensor supplied with a 1338 mm cable and a Molex connector. It is used on Worcester Greensource air/water heat pumps to monitor temperature at the point of installation and feed that reading back to the appliance control. The sensor forms part of the heat pump's temperature monitoring circuit, which the control uses to regulate operation.
Signs this part needs replacing
- Temperature readings that are erratic, fixed or clearly inconsistent with the actual system temperature
- The heat pump short-cycling or failing to modulate in response to temperature demand
- Fault codes or lockouts relating to temperature sensing on the appliance
- Reduced or inconsistent heating and hot water output traced to an incorrect sensor reading
- Visible damage to the sensor head, cable or Molex connector
Before you order
