There is no kit and if you don't know how to test and repair this type of electronics then you need to take it to a repair shop. Polk charges around $250 for the repair.

SOURCE: keeps blowing the fuse.

In more rare scenarios the 24v activated fan relay that is soldered to the circuit board can cause this same problem. I agree with Therinnaiguy, If the fuse is blown 90+% of the time there is a short in the 24 volt control system.

SOURCE: Thermal fuse keeps blowing

Mr. Larry (guru?)
The thermal fuse is just that It doesn't protect the circuit from over current although it certainly can open in that case. It is there to protect the board from overheating , thus the term thermal. The dishwasher could be allowing the water to heat too hot or the water heater in the home is turned up too much. The heater could also be shorted to case thus allowing it to be on even though the control is not calling for it especially if the polarity is incorrect to the dishwasher or the relay on the board could be welded closed so that the heater can't turn off even though the thermostat is satisfied. The best thing is to get a person who can check these things. You don't necessarily need to change the board with a fuse. I have changed many fuses with no other problems and verified that the machine was still working years later. sometimes the fuse just blows!

SOURCE: Polk Audio PSW350 Subwoofer keep blowing the fuse

The brown resin is glue that changed color due to heat and age. Rarely have I seen it cause problems. So unless you are having problems, No.

Hi I have a Polk PSW10 it keeps blowing fuse as soon as I plug it in after replacing fuse

Fuses blow when there's an overload. The most common cause is a shorted semi-conductor in either the power supply or the main amp stage.

Internal fuse keeps blowing out.

Suspect an overload in either the power section or the main amp semi-conductor. Look for parts that are damaged or get hot.
