rinkeswa Posted October 6, 2021 Report Share Posted October 6, 2021 I just inherited a Jayco 2004 Talon zx, very excited to join the lifestyle. I have familiarized myself with the instruction manuals and wiring and plumbing - the good news is everything appears to be working per the manuals. The water heater appears to be working a little too well as there is distinct steam rising from all hot water and I worry about scalding myself in the shower. The manual has drawings of two different thermostat manufacturers for this model heater but I can not find either thermostat anywhere on the heater. Can anybody tell me where the thermostat is located? Thanks in advance, sorry for the dumb question. Quote Link to comment Share on other sites More sharing options...
GlennWest Posted October 6, 2021 Report Share Posted October 6, 2021 Water heaters are small. 8-16 gallon depending on model. Has to be hot to supply enough. There are 2 thermostats In it. One for 120 v service and one for gas service. No adjustment. Just use little hot and more cold.

Kirk W Posted October 6, 2021 Report Share Posted October 6, 2021 (edited) Welcome to the Escapee forums! The most common water heater size is only 6 gallons with a few at 8 gallons so Glen is correct. If you open the outside access and look for this black foam cover, the thermostat is to the right and the left is the over temperature limiter. Note the label E.C.O. and just to the right T'STAT. There are adjustable thermostats for an Atwood water heaters but I have never used one.

Dutch_12078 Posted October 6, 2021 Report Share Posted October 6, 2021 The OP has a Dometic/Atwood GC6AA-10E 6-gallon gas/electric water heater as listed in the subject. Does the overheat occur on both gas and electric, or just one source. Both gas and electric thermostats are nominally set for 140 degrees F. If the thermostat fails closed though, the temp can go up to 150+ until the ECO, the over temp sensor, shuts off the gas or electric. Gas/electric Atwood water heaters made since 2003 use the same fixed thermostat and ECO set located on the front of the tank to control both heat sources.

rinkeswa Posted October 9, 2021 Author Report Share Posted October 9, 2021 thanks everyone for straightening me out. I'll actually measure the output water temp if it's 140 or so I should be happy. - great picture btw Quote Link to comment Share on other sites More sharing options...
