Cool room down at 2am, full pallet of stock inside, opening in seven hours. You've got two priorities — keep what's cold cold for as long as possible, and get a refrigeration mechanic looking at it as soon as you can. Here's the order of operations that gives you the best chance of saving the morning.
Step 1: Don't open the door
This sounds obvious but it's the most commonly broken rule. Every time you open a cool room door to check what's inside, the residual cold air drops out and warm air rolls in. A sealed cool room with stock at 2°C will hold below 5°C for hours; the same cool room with the door opened every fifteen minutes will be in the danger zone in well under an hour.
Resist the urge. The stock is fine right now. Opening the door is what makes it not fine.
Step 2: Check the circuit breaker
Find the switchboard and look for a tripped breaker on the cool room circuit. A tripped breaker is the cheapest possible cause — flick it back on and the system may simply restart. If it trips again immediately, stop and call. There's a fault that needs a technician.
Step 3: Check the thermostat and controller
If the unit has a digital controller, look at the display. Error codes often point straight at the fault — high pressure, low pressure, sensor failure, defrost issue. Even if you can't interpret the code, write it down. It saves the technician fifteen minutes of diagnosis when they arrive.
Also check that the thermostat hasn't been bumped or accidentally set high. It happens more often than you'd think.
Step 4: Call for emergency service
If steps 2 and 3 didn't bring it back, it's a refrigeration mechanic call. Across the Central Coast, including waterfront sites in The Entrance, Freezetech responds to commercial emergencies as fast as the road allows — weekday or weekend, daytime or evening, on a case-by-case basis outside normal hours.
How long does the stock have?
A general rule for food safety: stock is fine while it's below 5°C. Above 5°C for under 4 hours, it's usually still safe. Above 5°C for 4 hours or more, you're into the food safety danger zone (the NSW Food Authority sets these thresholds) and the stock has to be discarded. A sealed cool room (door kept shut) typically stays under 5°C for 4-6 hours after the system stops, depending on outside temperature and how full the room is — full rooms hold cold longer.
Minimising losses
If a fix isn't coming fast enough, the best move is to relocate stock into a working freezer or another fridge if you have access to one nearby. A neighbouring business will often help in an emergency. Save what you can, document everything, and the insurance conversation later is far easier with photos and timestamps.
