If you own a commercial freezer and the alarm goes off, it can be really scary. You don’t want to lose all of your food or have to pay for expensive repairs!
It’s important to know how to repair an alarm on a commercial freezer if this happens in your restaurant, grocery store, or other business. This is especially true if you’re not sure what caused the problem in the first place.
The best way to avoid these kinds of problems is to know how to troubleshoot them yourself before they happen. We wrote this guide so that anyone who owns a commercial freezer will know exactly what steps they need to take when their freezer alarms go off!
Supplies You Would Need –
- Longnose pliers
- Wire strippers
- Electrical tape
- Plastic covering/insulator (*for older models only!* [if you have a newer model please disregard])
- Screwdriver w/ plastic head so as not to damage your machine’s surface
- Metal wire clamps
- Cable ties
- Wire cutters, or a utility knife
The longest part of this process is going to be removing the old wires. To start, unplug your freezer and make sure its completely shut off before continuing with any other steps.
Make sure it has been turned off for at least an hour so that we can deplete as much power from inside as possible because if there’s still some left in there then you may get shocked when you touch something metal on the outside of your machine which would not only stop our repairs but also put us at risk for injury.
You are now ready to remove all the wiring from the back of your machine.
The metal will be very hot so make sure you have a rag to cover it and remember that just because this is not an electrical circuit, doesn’t mean we can cut corners on safety precautions! You may want to wear gloves as well if you have sensitive skin or allergies to metals for protection before touching any part inside.
How to Repair an Alarm on a Commercial Freezer in 6 Steps –
- Step One – After you’ve turned off the freezer, remove any food that’s still in it. You want to make sure there isn’t any lingering odor or bacteria from thawed meat and other foods.
- Step Two – Clean the alarm area with soap and water. It’s best if this is done by someone who knows how to use a ladder safely! If not, be careful when climbing up high so as not to cause damage or injure yourself.
- Step Three – Remove all screws holding the wire coverings over important parts of the device (including the thermostat) using both your hands and needle-nose pliers for those which are hard to reach. Make note of the parts so that you can put them back correctly later on.
- Step Four – After removing the screws, clean around the wiring again with soap and water to remove any dirt or grime which might have spread from when you touched it earlier. If there’s a lot of debris here you may want to use something like Windex so as not to cause further damage while cleaning up wires that need to be replaced.
- Step Five – Carefully cut away all old wire connections by gently peeling off the plastic coating until they are exposed but still connected at one end. Make sure that if this is for an older model machine your insulation isn’t causing any fire risk! The newer ones will only require cutting in some small areas where necessary so as not to create dangerous sparks.
- Step Six – Next, attach the new wire connections to each other in the same way as before making sure that they are securely attached and won’t pull off during use again. When connecting them together you’ll want to cover up any metal on the connection with electrical tape or plastic covering of some kind so that it doesn’t make contact with another point if there is an electric current running through this line.
If it’s for an older model machine only then wrap around your entire area where wires connect with insulation which will keep insulation intact while also keeping fire risk low!
For newer models just cut away any areas near enough to cause sparks when cutting apart old wiring but leave everything else covered up instead. Finally will be attaching our new wire to the alarm.
The best way to do this is by using a screwdriver and pushing it through the insulation on these wires which will make contact with the metal inside, then wrap cable ties around both sides of that area in order for them not to move or come loose when used again.
