Opening up the unit and spray them inside might help. Orherwise best to replace. The one used is the PEC12R 4220F S0024.But the 4120F S0012 might be safer as it has only 12 pulses per rev so each gray "stretch" is double as long. But it takes also twice as much rotating to change a value.Regards, Deve.

They are easy to damage internally if they are heated too high and for too long. Although hand soldering is not recommended, it can be done if you are careful.The datasheet for the PEC12R shows the soldering criteria.
