Whirlpool gold side by side runs constantly but shuts down for a second and restarts. All temps seem to be good. Compressor and both inside/outside fans shutdown and restart. I cleaned condenser coils and fan runs. Evaporator coils are lightly frosted not frozen and fan is running. I ran service diagnostic mode and every thing is good. I have measured the freezer temp -1 when set at 6 . Pulled thermistors and measured ohms. Freezer was 2,612 ohms at 77 degree F. Refrig side was 2,684 ohms at 77 degree F. I switched thermistors and re installed no change. Is this the electronic control board gone bad or something else. Thanks for any help
