RV refrigeration training topics include troubleshooting, theory of operation, the absorption cooling unit, leak checks, flushing the cooling unit, charging the cooling unit, assembly and disassembly, plugged boiler tubes, welding and replacing controls.
Depending on the amount of instruction desired, courses may run anywhere from five hours to five weeks. While some long courses may result in certification, the shortest ones do not. Some courses provide participants with the opportunity to buy tools for use during the course and afterwards.
Because course length varies so widely, so does the cost. The cost of a short five-hour course is typically between $400 and $500. The cost of a multiple-week course may cost anywhere between $4,000 and $8,000.
