RV Repair: compressor wont shut off, duo therm, spelling errors

Question
similar situation as one of your inquiries.  You say it must be bad control board and it's on the inside...silver...where exactly? in the air return section or ???.  I have Duo therm model 620425.321, serial # 339 30872.  I have to trip the breaker to shut the compressor off, thermostat has no effect on it. Thank you in advance for your reply..

Answer
as long as its ducted and not a numar you should be able to remove the inner assembley and and you should be looking stright up at the a box with a possible part number of 3107541-009 if it has celing controls thats a different deal. So isit ducted or non ducted
