10 Reasons Why Your Oven Won’t Turn On And How To Fix It

An oven that breaks down in a busy commercial kitchen can cause havoc and missed sales. Since the oven is an essential tool for preparing meals, it is imperative that you make sure it runs well. Understanding the functions of the various elements and how to troubleshoot issues can be very helpful when dealing with issues linked to commercial ovens. This post will discuss the frequent causes of oven malfunctions, the essential parts involved, and practical solutions.

Understanding Commercial Oven Components

A knowledge of some of its main components is required to diagnose and repair oven problems. Here’s a brief overview of the critical commercial oven parts:

• Heating Elements: The sources of heat production are these. Models can have bake and broil elements, or both.

• Thermostat: It controls the section of the oven that keeps the heat controlled by the heating elements.

• Control Board: Usually the control board is referred to as the brain of the oven because it has to take care of everything like temperature setting and timing.

• Igniter: It starts the gas in the gas oven heating process by lighting the gas.

• Door Switch: It makes sure the oven can’t run with the door open, increasing safety. 

• Thermal Fuse: An overheating cut-off that will turn off the oven if it becomes too hot.

• Power Supply: This includes wiring, plugs, and fuses which deliver electrical power to the oven.

10 Reasons Your Commercial Oven Won't Turn On and Fixes

These are the typical causes of your oven not turning on. To get your kitchen back up and running, we'll offer workable solutions for every problem.

1. Power Supply Issues

An oven that doesn’t turn on is often due to a power supply issue. The cause may be blown fuses, tripped circuit breakers, or bad wiring. 

Solution:

Look at the circuit breaker, and make sure it hasn’t tripped. If that’s the case, reset it and hope the oven is working. Look at the plug and power cord to make sure they don’t come off, you may need to replace them. To solve power problems, make sure all the parts for industrial ovens are in working condition.

2. Faulty Thermostat

The most likely cause of an oven that won’t turn on is a broken thermostat. But if the thermostat is bad though, the oven won’t heat up or turn on at all. A thermostat controls temperature.

Solution:

You can use a multimeter to measure the continuity of the thermostat to find out what’s going on. Replace it with the right part if broken. Make sure the thermostat you’re using is compatible with the equipment you own.

3. Defective Heating Elements

An oven’s heating components are essential to produce the necessary heat. If these elements burn out or are damaged in some way, the oven may simply refuse to turn on.

Solution:

Look at heating components for marks of impairment, for example, chips or fading. They will have to be replaced if they are worn out. Routine inspections, and prompt replacements, remove much of the potential of unexpected downtime in high-volume kitchens.

4. Malfunctioning Control Board

Practically the brain of the oven is the control board, which controls all of the operations. If the oven is damaged or faulty, it will not respond to those, such as turning it on.

Solution:

The control board could be the problem if the display panel doesn’t light up or the buttons don’t respond. This time it might require a replacement. This repair is so complicated that you’d be advised to hire a qualified expert.

5. Gas Supply Problems (For Gas Ovens)

Gas-powered ovens can sometimes have problems with the gas supply and won’t start up. A gas line or gas regulator may be blocked by a closed gas valve.

Solution:

The first step is to ensure there are no obstacles in the line and the gas valve is open. If these fixes don’t work, you might have to check the gas regulator. Because handling gas components requires expertise and the technician needs to ensure that no leak remains in those components, do not hesitate to call a qualified technician to check for leaks or defects.

6. Blown Thermal Fuse

Safety devices and thermal fuses are devices to protect ovens from overheating. If the thermal fuse blows, the oven power supply will be cut off and the oven will not respond.

Solution:

Use a multimeter to find out if the thermal fuse blew. If this is the case, the oven should power back up if you replace it. They are inexpensive fuses, but they are important for safety.

7. Igniter (For Gas Ovens) Faulty

In gas ovens, the igniter is the starter for the burner. If it's weak or doesn’t work properly, it may not be enough to light the spark that will turn on the oven.

Solution:

Try to start the oven and see if the igniter glows. If it doesn’t glow, or the oven doesn’t ignite, you’ll need to replace it. For gas ovens to work properly, the igniter must work properly.

8. Door Switch Malfunction

Ovens are usually fitted with door switches and other safety features. The oven won’t work if the door is not shut properly or if the switch is faulty.

Solution:

Check the door switch and see that the door is shut tightly. If the switch seems broken, it must be replaced. Be sure to get the right switch for your particular oven, as components differ from manufacturer to manufacturer.

9. Timer or Clock Not Set

In some ovens, the timer or clock must be set correctly for the oven to turn on. If these aren’t set, the oven may refuse to power up.

Solution:Double-check the timer and clock settings. Refer to the oven’s manual to see if resetting the clock or timer will solve the issue. Ensuring these settings are accurate is a quick fix that can prevent unnecessary downtime.

10. Loose or Damaged Wiring

Wiring issues are common in busy kitchens where ovens are moved or exposed to high temperatures. Unstuck, broken, or loose wiring may keep the oven from turning on.

Solution:Take a close look inside the oven at the wiring around the heating elements and control board. If any wire is broken or loose you’ll need to replace or reconnect them. Wiring repairs are best left to a certified technician because of safety risks.

A commercial oven that will not turn on is a great inconvenience. If you know the common causes of this problem, you will be able to solve it yourself or find out which specific problem needs to be solved by a professional using the troubleshooting techniques described in this article. Don’t forget that proper maintenance and the use of high-quality commercial oven parts are vital to the prevention of future malfunctions and to proper equipment operation.
