What it is
The Baxi 7739900 is the control cover assembly used on the System 800 range of Baxi gas boilers. It is the outer casing panel that encloses the control panel and its associated components, protecting the controls from dust, knocks and accidental contact while giving the appliance its finished front appearance. The assembly is supplied by Baxi as a direct replacement for the original cover fitted at manufacture.
Signs this part needs replacing
- Visible cracks, splits or holes in the control cover
- The cover no longer seats or clips correctly against the casing
- Impact damage from tools or accidental knocks during servicing
- Heat marking, discolouration or warping around the control area
- Broken or missing retaining fixings that leave the panel loose
Before you order
- Confirm the GC number and the serial number suffix of your appliance, as the cover differs between build variants
- Check the alternative number 1795786 against any markings on the existing part
- Inspect the fixings and any seals around the control area and replace them if they are worn
