Fault Finding & Multimeters Course

The Fault Finding & Multimeters Course is designed for installers who want to improve fault finding, servicing and repairs for their customers, or maybe change from installing and move into breakdowns which will make more money. It also caters for new students coming into the heating industry, who have little or no knowledge of fault finding and diagnostics.
