Toe kick heaters, Marathon

[Grizz]

Naw... I'd rather fix the OEM installation! If not, I'll run the Webasto rather than using add-on equipment. Thanks anyway for the suggestion!

Grizz,

Somewhere there is a control relay that applies 120V to the heaters when the SMX control calls for electric heat. It's anyones guess as to where it is. The easy way to figure it out would be to call Marathon. You could also have someone toggle a working toe kick heater while you move around the coach listening for the relay. There's a good chance where one is you'll find the others. CC, for example, puts all of the 120V relays in the same location under a cabinet panel behind the main circuit breaker panel.

Good Luck,

[Grizz]

Thanks Gil:

I can hear the relay behind the CB panel when heat is called for, but there must be an open from the relay forward. The washer and dryer are right behind the panel so I'll have to figure a way to pull the panel forward. Oh joy!

Grizz,

I didn't hear you make mention of the bath heat switch located on your light switch panel in the bath. That controls the toe kick heater in my 01 Marathon.

[Grizz]

Switch it on. What a novel idea! Duh! Okay, thanks for letting me know about that. One inpo heater is now operating!

Thanks so very much!

Don't feel bad Grizz. I had a 93 several years ago, and I stayed on the phone with Marathon for over 30 minutes troubleshooting the same heater. After removing the heater, the Tech finally asked me to flip the wall switch again. That was the first time I knew the switch existed. I didn't realize the 01 was like my 93 or I would have mentioned this earlier.

Thanks for the encouragement!

Any idea how to 'flip the switch' for the bedroom heater? I checked all the wall switches. The relay behind the electrical panel energizes when the SMX calls for heat, but the heater doesn't come on. Could be a defective heater I suppose!
