What it is
The Vaillant 0020018138 is a fan proving switch, supplied under the Huba name, for Vaillant domestic heating appliances. It sits in the fan and combustion air circuit and reports changes in activation or flow back to the appliance control board, so the boiler can confirm the fan is running before and during a firing sequence. It is a pressure switch type component, listed by Vaillant under spare part type Pressure Switches.
Signs this part needs replacing
- The boiler locks out or fails to fire even though the fan can be heard running
- Ignition is attempted and then the appliance shuts down shortly afterwards
- Intermittent lockouts that clear on reset and return on the next demand
- A fault code relating to fan operation, air pressure or proving appears on the display
- The appliance runs only when the fan proving circuit is bypassed or bridged during diagnosis
Before you order
- Match the part number 0020018138 against the number on the existing switch or the appliance's parts list
- Confirm the appliance model and, where available, the serial number before ordering
- Check the appliance's installation and service documentation for any seal, gasket or O-ring that should be renewed when the switch is replaced
