Dear Sirs: I purchased a standard Cold Machine in the late '80 with a horizontal Freezer unit SFH-1, the Compressor unit is a CM-12 type. My problem is that neither the Fan nor the Compressor will start. One weekend all was fine and the next weekend nothing worked. The unit was on while I was absent from the boat. I noticed that the tube connections face to my front, while the electrical connection face the back of the unit. and since these electrical connections are close against the hull, I find it very hard to see wether or not the fuse has blown. I noticed your latest designs have corrected this problem by having the electrical connections face the same way as the tube connections. Please email me instructions with drawings, if possible, on how to get at the fuse for replacement. My owner manual mentions the fuse, but provides no sketch nor instructions on the subject of fuse replacement. What a pitty! Also, please tell me which Controller model would I need, in case the fuse is not the problem. Thanks, Frank Maier
