Hi Rita,
We would likely need to start with figuring out the manufacturer, as we’re not able to tell much from those codes. Many brands look alike these days, however there may be a manufacturer label on the top side of the motor housing. If so, try using a mirror to figure out the brand / model of the fan without having to remove the fan or take it down. Failing that, you may have to “drop the canopy” – which means lowering the shroud, which generally covers the mechanical and electrical connections at the ceiling.
Let us know, thanks
Regards,
