In some cases it may be fixable like for example if the footswitch is a 3PDT but only two of the poles have been used, you can just simply solder the wires from the faulty pole onto the unused but good pole , but I usually just replace the switch with a new one, the pop you hear on activation is usually due to charge build ups in the input coupling cap of the pedal's circuitry, you can fix that by soldering a 1M or 2M2 1% metal film resistor from the tip connection of the input socket to the sleeve connection of the input socket, doing this will allow the built-up charge to bleed-off to ground, since the resistor is very high in value it will not have any audible effect on the sound.
