Laars Endurance boiler troubleshooting ( EBMpapst G1G144-AE13-05 Laars 2400-524 blower repair)

Today my boiler failed completely after acting up for over a year (no power). Found blown 4A inline fuse by the main 24VAC power transformer. New fuse blow out right away. Found that blower motor causes the shortage. Removed blower module and recorded short video how to fix it. You will need: 2pcs 47-100uF 25-50V high quality capacitors (105C minimum, better tantalum, SMD capacitors have confusing polarity!) 2pcs MTD20N06HD 20N06HD (get extras just in case) 2pcs 47ohm resistors (just in case) a bunch of 4-5A car fuses (don't put more than 5A!) 470-1000uF 50V capacitor (was still good in my case, but I had faulty 4700uF 50V capacitor in series on previous board) Multimeter, soldering iron and heat gun (to heat up axle to put blower wheel back) My blower motor is 24V DC (16-28VDC). So, you can hook it up to old laptop charger to test it. Just be careful with polarity! Also, carefully check ESR for all capacitors on the rest 3 electronic modules (Fenwal 35-665908-115, small 24VAC to 20VDC rectifier board behind display and especially inside temperature display LP-FX05P01-120D. So, get ready a bunch of 25-50V capacitors. It should prevent/fix other issues you may have. Good luck!
