My caravan aircon is malfunctioning. The thermostat appears to cut in for 5-10 seconds then cuts out. This continues for as long as the unit is left on. The unit is a DOMETIC mod# CAL 136.312 aprox 6 yrs old. Can you please assist as to what the problem is, and an aprox cost of repair. I am located in Berwick, Vic. Thank you for your assistance Doug CURRAN
