Temp anomoly

I also thought my 55 had an unusual heat cycle so I ran a test with just the probe and an empty unit. The results were

15 min - 155
30 min - 260
45 min - 312
60 min - 266
75 min - 242
90 min - 221
105 min - 206
120 min - 224

From this point forward it held between 212 and 240f. I suspect it has something to do with the cabinet shell reaching a certain temp ad then things settle down. The internal temp probe rests against the shell and possibly senses the cool shell until the shell actually reaches the 225f range consistently. Just my non expert opinion....

It'll settle,don't worry.

A little aging on the walls helps,also.

As long as you are getting sufficient temp,I wouldn't check it.
