I have Diplomat integrated fridge freezer model APM 6855 ?

Hi there, I have the fridge/freezer above and is now showing an "H" for fridge temperature. I cannot set temperature for fridge or freezer, though freezer is working ok. It's been suggested on other sites that the thermostat might be too hot and need replaced. If this is the case would you have any idea how much it would cost or best getting a new one.

Press and hold Cooler button to reset fridge, Press and hold freezer button to reset freezer. The buttons are at the top of the fridge inside door.
