Water Bay Heating--Thermal Switch Question

[CaptPat]

I've noticed that the thermal snap switch for the heater in the water bay is "dangling" from the ceiling of the bay. Will that prevent the switch from properly actuating the heater or does it need to be solidly mounted the a surface?

Thanks

I don't think it will stop it from working unless a wire has already pulled loose, but you really need to re-attach it so that it does not get damaged or pull a connection loose.

Is this the Anti-Freezing heater?

If so it works best that way, so long as all the wires are attached.

Mine lays on the floor of the bay.

I would do as Gary suggested that way you will not have a problem with wiring breaking down from flexing.

Thanks, I'm not sure it was ever attached, the wires are just staple to the ceiling of the bay. I'll afix it more permanently the next time I dive behind the bay.

Pat, there are two snap disks in that compartment. The one that is dangling, I have the same situation, does not control the ceramic heater. The one controlling the ceramic heater is on the floor of the compartment just to the outboard side of the winterizing pump. Look right up against the front wall of the compartment.

I don't know what the other snap disk controls. On our rig, and I assume yours as well, has a heating coil from the Aquahot system in the compartment. I don't know what turns it on but I assume it comes on with either zone 2 or 3 heat.

I have a remote temp sensor I put in the service bay and at times I see the temp get as high as 70 deg before the ceramic heater shuts off. Don't like that but with the snap disk on the floor I can see why that happens.

If you figure out what the hanging snap disk is let me know - I haven't figured it out.

For info I had to replace the thermal fuse in the ceramic heater last year. I can give you the details via email if you like.

Thanks for info. Please pass along the info on replacing the fuse in the ceramic heater, don't know that I need it but better to have in case I do.
