Hey Guys,
I got the water heater out of my coach today, and its in great shape!! But I want to replace the heater element? I found 120 volt 1500 and 2000 watt elements?
Im leaning toward the 2000 Watt version?
Thoughts?
Thanks,
Steve

Just picked up my '74 Painted/Canyon last week, so I'm still new at this. Where exactly is the hot water switch going to be? I looked in the hallway cabinet location where the breakers, inverter and house fuses are. Was that the stock location for all models, and being an RV noob in general, what do I have to punch in on Amazon to find these elements you speak of?

You have the correct location for the water heater switch.
The heater elements are available at Home Depot, Lowers, Menards, etc.

HOT WATER HEATER TIMER
I got this great idea from a GMC Cascader. He got tired of his hot water
heater coming on when there was no water in the tank and burning out the
element. He replaced the switch with a mechanical timer that fits in the
same location.
I did the same. Now we have an indicator that the heater is on and a
safety drop out that will require the owner to turn on the heater when
the coach is plugged in to the AC.
Lots of heater elements have burned out because of this ( Mine was), and
causes the generator to come up under load (which is not good).
Here are pictures of the installation.

Due to the fact that some places don't have 50 amp service, and the fact that the 50amp pigtail is so darn stiff, I changed mine out to a 30amp style. This allows for a much easier and longer pigtail.
Anyhow, the reason I say that is the 1000 watt element still heats the water up plenty fast, and leaves wiggle room when operating on 30amp service.
I've even run it off a Honda 2000 inverter generator.

Gene,
Further down that page there's an entry "Windshield Wipers rebuild " which
I originally wrote MANY year ago. You need to remove it now since "Mr.
Hydraulic Wipers", Bill Telgen, passed away about 3 years ago, leaving the
entry irrelevant.
Thanks,
Ken H.

Andy,
But if you blow the extra money (~3$us) on the 4k/240V element, it will only draw 1K on 120V and it will not have the hot surface scale issues that the 1K does because it will be running much cooler. The only problem is that you have to know how long an element you can install. If you get one that is an inch too long, it will take a whole lot of teflon tape to close that gap and it may still drip.

Kelly,
Yes, the GMC fit coaches had a toggle (like a light switch) in that space to shut down the water heater. It is usually accompanied by the outlet for the converter.
Though I don't think anybody here was born knowing everything there is to know about GMC motorhomes, I do have a candidate in mind...
I was new here not that long ago and found I had suddenly joined an amazing community. More about that down the page.
If you go to Amazon key in "water heater element" but before you buy, you best crawl into the head and remove the old one and stick a ruler into the tank you really don't want to get an element that is too long (see my remarks to Andy). You may also have to buy a part 07223 at Amazon because most heaters the age of our coaches were square flange and about all you can buy anymore are the screw in.
Now, back to being new here.....
Welcome to the group, family, cult, asylum......
You really need to hook up with other members close to you and get to a rally or two so you have faces that go with the names.
You have just become a member of a most amazing community. If you haven't gone to Bdub's page and collected a current copy of the Black (aka GMC assist) list do so. These people enjoy helping others keep coaches alive. The only way I have seen to annoy them is to ask for advice and then ignore them. I do not write this to offend any of those of us that do Facebook, but this is a much different group. There is a lot on Facebook, but those that the really technically capable are here and they aren't into the social network stuff. Some of us write there, but the format does not lend itself to technical issues. There is just an amazing amount of support here just for asking, just try to be clear what you are asking. Because this group is so much like that of the watermen that are my world, I have taken to welcoming new owners much as any new owner or vessel is traditionally welcomed there. So,
May the Good Lord bless this coach and all those that set forth within her.
Welcome Kelly

Hey Guys...
More "water heater drama" LOL
I took my tank to my buddy to clean and flush, should have it back by Tues. this week.
Went to buy a new heater element and a 1500 watt 120 Volt on is half as long as the original? Should that matter?
Next problem, I cant find replacements for the two switches (Thermostat and reset maybe? One has a red button (reset). Anybody know where to find replacements?
I think this might be the replacement for the thermostat:
Atwood 92943 Water Heater Thermostat
http://www.amazon.com/gp/product/B00A2TECR6?psc=1&redirect=true&ref_=ox_sc_act_title_1&smid=ATVPDKIKX0DER
But I cant find the reset switch replacement...
Thanks for the help again...

Amongst the many pretty things that JmK has for sale, he has replacements for the Atwood water heater thermostat and the "red" button. Call him, he does not bite.
