Blown Capacitors On Sonos Play 1 Sonos Play 1
Chosen Solution Both caps on the high voltage side are blown. PCB markings MOV301 and TH301. At least I suspect they are both capacitors… hard to see since they are burned out… does anyone know what to order and replace with? First of all these are not capacitors. The one marked MOV301 is a Metal oxide Varistor and the one marked TH301 is a thermistor. These are both protection devices. If they are defective, than there is probably something else wrong with the unit that caused these to fail....
