I know this is an older thread but obviously I’m at that point in the life of my thermostat. However, the numbers on the top of my capacitors are different from the ones in your pictures. How do I find the correct capacitors for my circuit board? So I have 3 on mine. 2 of which are the same. The 2 larger ones read:

220

HHB.

K78

And the smaller one reads:

E372

47

10V

Any help would be awesome. Thanks
