Great quiz! And I had just left in prior comment today a request for refrigeration type questions. Troubleshooting type questions would also be appreciated. Thanks for taking time to create these quizzes.

Typically, a cold control senses coil temperature in a reach-in to ensure off-cycle defrost. In a walk-in, a cold control normally senses box temperature.
