I have a unit that is a bit older : So i believe out of warranty - but question is 
Suddently the Unit does not come on :
Checked the adapter and its getting 29V (so we’re good there)
Opened the box and checked the board and its getting 29Volts tot he input connector but does not go past the Fuse (F1) on the PCB - I have a Rachio 2nd Gen
Any ideas on what fuse that is ? or replacement board ?
