Commercial Oven Troubleshooting Tips

Whether you own a small restaurant or a high-end luxury dining establishment, the appliances in your kitchen are literally the backbone of your business. 

After all, without them, you wouldn’t be able to serve any of the delicious food that your customers come to you for. 

With that said, when your oven breaks down or isn’t working as well as it once did, it can leave you with a serious headache, not to mention the fact that it can put a serious damper on your business. 

In the following article, we’ll be looking at a few common oven issues and how you can go about troubleshooting them on your own, without needing to call in professional help.

Commercial Oven Won’t Heat

If you’re having an issue with a commercial oven that isn’t heating up at all, then the first thing you’re going to want to check is that the unit is, in fact, properly plugged into a working power source. 

Make sure to check your establishment’s main electrical panel to ensure that no breakers or fuses have been tripped or blown. 

However, if you’ve ruled out an issue with your power supply, the next thing to check is that your oven’s elements are working properly.

Faulty Heating Elements

Because of the amount of use they get, an oven’s elements are prone to wearing out over time. 

Therefore, the next thing to do is to visually inspect the oven’s element for signs of damage or corrosion. If you can see the element is visibly blistered, separated, split, or crack, you can almost guarantee that this is the source of your problem. 

Fortunately, replacing a faulty element is not a huge job and can either be done by yourself so long as you’re able to find the right replacement part.

Commercial oven thermostat

Malfunctioning Thermostat

Your oven’s thermostat is the component responsible for shutting the heat off once the inside of the oven reaches a certain temperature, as well as turning the heat on when the oven starts to cool down. 

Therefore, if the thermostat isn’t working properly, your oven isn’t going to cook at the correct temperature, which often leads to either burnt or undercooked food. 

Start by checking your oven’s thermostat to see that it hasn’t been knocked loose or damaged during cleanings. Also, make sure that it’s not touching the oven’s interior, which might also contribute to faulty temperature readings. 

To check if the thermostat is working properly, you can use a multimeter. 

When it comes to diagnosing electrical issues like this, we usually recommend letting one of our trained technicians come out to give you a hand.

Commercial Convection Oven Heats Unevenly

The most common reasons for a convection oven that won’t heat properly and won’t cook food evenly is either a faulty convection fan or a faulty heating element.

Convection Fan Is Not Working

When in use, your oven’s convection fan is used to help circulate hot air throughout the inside of the unit. This helps distribute the heat properly so that your food will be cooked evenly on all sides. 

However, when this fan isn’t working, the heat won’t circulate properly, often leaving you with undercooked or unevenly cooked food.

Burnt Or Damaged Heating Elements

As mentioned, a faulty heating element is a rather common occurrence, especially with commercial ovens used continuously day after day. 

The most obvious way to tell a heating element is faulty is if it’s visibly blistered, broken, separated, or charred. If you notice any of these signs of damage, you’ll most likely need to replace your heating element.

Gas Oven Won’t Light Up

Due to their superior performance, gas appliances are often preferred by chefs, especially in commercial settings. 

However, because of the way they work, and just like any other commercial appliance, gas ovens are prone to occasional wear and tear. 

With that said, if you’re experiencing an issue with your gas oven or cooktop, and you suspect an issue with your has supply line, you mustn’t attempt to resolve the issue on your own.

Dirty Elements

In some cases, especially if it’s been a while since you’ve cleaned your oven, your element may be gummed up with food particles and other debris. 

Therefore, before picking up the phone to call us, start by giving your elements a thorough cleaning. In some cases, the burner’s small gas holes may become clogged, which will prevent the flow of gas, resulting in your issue.

Broken Ignitor

Alternatively, a gas oven that won’t light is often caused by a broken or faulty ignitor, which doesn’t provide a spark to ignite your oven’s gas supply. If this is the cause, you might hear repeated clicking when you attempt to light your oven, or the spark itself may appear fainter than usual. Either way, if your ignitor is faulty, you’ll need to have it replaced.

You can attempt to swap out this component on your own. However, since your commercial oven might still be covered under warranty, it’s best to contact a certified appliance repair company.
