Maytag MSD2454GR. Freezer not freezing and fridge not getting cold... there is a click we hear

Question

Freezer not freezing and fridge not getting cold... there is a click we hear then like 8 seconds of something happening maybe?? then another click...

fridge is not cold, looking into the freezer I can see ice building up on the back panel. Last time this happened I had to buy a new circuit board ($150). Not sure why but the defrost heater must not be working.model # msd2456dew
