TC1 (used for CP4 bake contoller) displaying invalid value then valid value then .....

I noticed that the displayed value in the TC1 field was "#..." or absent a numeric value this morning at 0110 hrs. during a random check.  I monitored for 10 minutes and noted displayed values as 

TC1="#..." TC2=85.5 TC4=83.0 %(can't determine due to pixel resolution) 

TC1="#..." TC2=85.8 TC4=83.2 %(can't determine due to pixel resolution) 

TC1="#..." TC2=85.7 TC4=83.1 %(can't determine due to pixel resolution) 

TC1="#..." TC2=85.6 TC4=85.2 %(can't determine due to pixel resolution) 

TC1=99.9 TC2=85.5 TC4=85.5 %71 

TC1="#..." TC2=85.9 TC4=83.3 %76  

Thus, displayed value of TC1 is alternating between gibberish and valid values.

It appears it doesn't like to read out three whole #s.
