What it is
The Baxi 5112321 is a fan kit manufactured by Baxi for use in its 70 HE and 80 HE appliances. It is classed as a fan impellor and fan assembly spare, and it sits on the combustion air path, moving air and flue gases through the appliance so that combustion stays stable and the flue clears correctly. A working fan is what allows the appliance to prove airflow, ignite safely and run without locking out.
Signs this part needs replacing
- The appliance locks out shortly after a call for heat, or fails to reach ignition at all
- A fan or airflow fault code is shown on the appliance display or diagnostic LEDs
- Grinding, whining or rumbling from the fan housing when the appliance starts up
- Intermittent running, where the fan starts and stops or the appliance cycles on and off
- Overheat lockouts or repeated resets that trace back to poor airflow through the appliance
Before you order
- Confirm the appliance model and GC number from the data badge, then match it against the compatibility information for this part
- Check the part number 5112321 against the number printed on the existing fan assembly before removing it
- Inspect the fan mounting gasket and sealing washers, and renew them if they are compressed or perished
