Please forgive the novice question... one of the two 10A/250V fuses blew on the disconnect to my AC compressor unit (photo 1). I went to the big box store and they only had 20A and 30A fuses so I got the 20A and replaced the one blown 10A fuse with the 20A, so now there's a 10A and a 20A on the dual line disconnect. They're both Class RK5.
The unit is running again fine but is this okay long-term? Or should I go out and immediately find a matching, 10A fuse? I included photos of the fuses themselves and the inside of the disconnect for reference as well.
