Most common repairs needed to fix a LG cooktop
Electronic Control Board Replacement
When the cooktop is not working, a defective electronic control board could be failing to send current to surface elements. Electrical relays close contacts to send current to a burner when you set a burner to heat. When the internal logic or internal circuits in the electronic control board fail, current won’t flow to the burners. When your cooktop has power but none of the elements work, have a Sears Home Services Technician check the electronic control board and replace it if it’s defective.
Igniter Replacement
A broken igniter prevent burners from lighting on the cooktop. Some cooktops use an ignition system that reignites burners when the control doesn’t detect a flame on a burner in use. When a cooktop uses electronics to sense a burner flame, a broken igniter can short out electronics or damage other components in the burner ignition system so the cooktop won’t work. Have a Sears Home Services Appliance Repair Technician examine and repair your cooktop when it isn’t working.
Infinite Switch Replacement
When the cooktop is not working, you may find that the problem is caused by a faulty infinite switch. The infinite switch has electrical contacts that turn a surface element on and off and controls the heat level of the element. When internal switch contacts short out, the electrical circuit breaker will trip and prevent the cooktop from getting power. When you’re unable to reset the circuit breaker because it trips again as soon as try to reset it, you can suspect that faulty infinite switch may be preventing the cooktop from working. Have a Sears Home Services Technician examine and repair your cooktop.
What to expect when you experience an LG cooktop not working issue
How is the not working problem fixed?
Correcting most not working problems usually involves replacing the electronic control board, igniter or infinite switch. However, there are many potential causes, so a thorough diagnosis is key to fixing the problem. An accurate diagnosis is essential to understanding how much the repair will be.
Sears Home Services recommendations for a cooktop that is not working
When the cooktop is not working it can be for many reasons. To avoid replacing unneeded parts, we recommend scheduling LG appliance repair with a local Sears Home Services cooktop professional who can perform diagnostic tests to identify the root cause of the problem. Our technicians are experienced at diagnosing all types of cooktop failures.
What to look out for with a cooktop not working diagnosis
Diagnosing modern appliances without proper knowledge and training can be difficult. Without using proper diagnostic techniques, fixing your cooktop problem will only be achieved through changing parts on a hunch. Appliances, especially in the last 10 years, have become extremely advanced, and many models have electronic parts that are difficult to test. DIY repairs on the latest appliance models are becoming increasingly difficult.

fixed my oven within minutes!
i had previously had a technician out 3 times in the past 1 1/2 years, who was chosen by my home warranty company. The oven never worked, it was always a temporary fix. Shareef listened to the issues i was having and what i thought was the problem and fixed it within minutes! The oven works perfectly now, it does not turn on and off any longer and all 4 burners are hot. He was personable, efficient, and a true professional.
