Re: chiller fridge
If it is in a cold garage around 5 – 8c it no worky,they dont pull down as cold as standard refigerators and if in cold ambient they have no need to come on although internal fan normally runs constantly.
Mechanical thermostat is usually inside on the back plate,often dont like being moved,could check for continuity,might be access from the rear by removing panel.
If it has a digital controller at the bottom its a different issue,might be an on off button on it to press?.
What make ?
