Hi,
Welcome to Justanswer … my name is ***** ***** I will help you today!
I’m sorry to hear you're having trouble with your appliance; I know that can be frustrating.
Hopefully, we can get this resolved quickly.
Please ignore the automated phone call request.
If the right side plates work fine then it is the the Left side control that is faulty and will need replacement.
With these hobs there are only two things: plates and control, plates usually never go bad.
The cost of repair will be around £150 including parts.
