Marine Airrrr does not heat

[timjet]

My fwd Marine Airrrr unit suddenly stopped heating. The fan and water go on but just cold air. Also the lt on the control unit that you use to set the temp that indicates the compressor is on does not illuminate. Water flow is normal and the aft unit works normally.

Check the fuse in the control box. Mine did the same in November. The charge was good and there was no explaination for the fuse blowing.

I had a marine air unit with similar problem, wouldn't cool or heat. The culprit was a defective over temp switch.

Ok thanks guys, I'll check for a blown fuse and over temp switch?
