huffypuff Report post Posted November 26, 2018 I had the basement heater fail to come on causing the water to freeze the last few years. I have a backup electric heater that use 120 v but it will be good to have the system installed working. The main problem is when the cargo heater fail to come on it freezes the pipes and we end up without water. The reason why is the snap disk thermostat may or may not turn on as happen in Delaware during January 2017. I pulled into the campground in zero degree weather and the first thing I noticed was no water. Second thing was no cargo heat. So the next day we were faced getting a backup heater to thaw things out. No fun walking in freezing weather to use the restroom. I had a left over thermostat from a old garage heater one decided why not go with a real thermostat with more control. I didn't know how to put description after each picture so I hope you can follow in the order it was uploaded. 1 Snap disk, 2 Wires prepared for installation, 3 Wires installed for thermostat, snap disk disconnected, 4 Access panel being prepare for thermostat, 5 Access panel installed 6 Thermostat installed and set to 55 for testing, can be set as low as 35 but will be set at 40. 7 We have a working cargo heater Share this post Link to post Share on other sites

hermanmullins Report post Posted November 26, 2018 If you want you could install a "Freeze Guard" like the do for Swimming pools. It will power up the pool motor when the temperature drop below 36 degrees F. It can be plugged into any 110 Volt outlet in the coach or shore power. I had one on our pool when we lived in the city.

f433921 Report post Posted November 26, 2018 The heater on Huff's rig is 12 V DC. I had a similar problem on my rig which has the same setup as Huff's, I was able resolve the problem by cleaning all of the connection in the circuit. The thermostat in the control circuit not the power circuit to the heating element. Jim Share this post Link to post Share on other sites

It could of been the connection there but i didn't want to take a chance. Once its frozen too cold to work on. This way i can test the system before hitting the road.

f433921 Report post Posted November 27, 2018 I like the adjustable thermostat that you installed and should mine fail again I will install one. Thanks for sharing your good idea. Jim Share this post Link to post Share on other sites

Thanks for sharing your good idea. Jim It a simple 2 wire magnetic switch stat that can be used in barns to prevent freezing. That's why it go down to 35 but max at 75. Not a normal house thermostat but something you will find at farmer supply. Share this post Link to post Share on other sites

huffypuff Report post Posted December 5, 2018 Now I can attest to the fact that this modification works. Last few days we had cold weather as low as 28 and the thermostat was turning it on and off as it should. Share this post Link to post Share on other sites
