I went on my first solo refrigeration service call today and it was stuck in defrost. I turned the wheel until it finally clicked on, took out the timer screws and let it run. Called boss and told him what was up and he said to just let it run without defrost until we get to it next week (probably not until Wednesday). I'm sure I should have gone and gotten a new defrost timer and put it in, but I'm still just a noob doing what I'm told. Is it OK to leave it running without defrost for 5 days?
