Coleman air mattress came apart and has big hump in middle'can it be reparied

You should exchange it from the dealer. If it remains under the warranty then no charges apply to you. For any other help related to the mattress, you can visit: http://www.refreshmattress.com/

if this is an air mattress a baffle has blown or ripped internally

There is an intake port and an exhuast port on your Coleman quick pump. To determine and differentiate you need to turn it on and the one that is blowing air out is the exhaust that you would use to inflate the mattress. That leaves you with one other orifice that is taking air into the pump body. If you put your finger over that one it will suck down like a vacuum cleaner hose. That is the one that you want to attach the plastic adaptor nozzle to, and then hold the nozzle on the fill port of the air mattress. It will come down and into a vacuum state when it is all the way exhausted. Once completely deflated, they are much easier to fold back up and stow away. If you're at home and own a vacuum cleaner with a hose, save the batteries on your pump and use the vacuum cleaner. It will take about thirty seconds with that. Good luck with that.

People suffering from back pains find sleeping on an air mattress helpful at times. Air mattresses give you the ability to adjust the firmness of your mattress to accommodate you specific needs.

Hi rh57...

I will recommend that you use some contact cement, and a piece of thin plastic like a plastic drop cloth, shower curtain, etc.
Cut the plastic piece that will be using as your patch about 1" X 1" square.
Locate the hole in the air mattress, deflate air mattress, apply contact cement lightly to the air mattress approximatly 1" X 1" and the piece of thin plastic material you will be using as the patch over both entire surfaces of the patch and mattress...let it all dry about 20 mins.
After it is dry then apply the patch to the hole in the mattress, apply a weight to the top of the patch, let sit about half an hour and you are done
Hole fixed
Please take time to rate me thumbs up

Hello.
The fitting goes on the air inlet side and causes the blower to pull the air out of the mattress, that is, you use the same pump to reverse the air flow.
Best regards, --W/D--

Is it battery or electricity operated? You might need to replace the battery or hook it up to the right outlet. Follow the instructions in inserting it to the hole. Make sure you press the deflate button and not the inflate button.

If the pump device is really not working, you can temporarily manually deflate the air bed by unhooking the air release nozzle. Press it slightly to allow the mattress to deflate faster. Step on the mattress lightly to force air out a bit.

i took the whole dash apart once to change my radio. some of the wires inside the dash are either for the emergency lights, air bag or temp sensor. that small hump on the top of the dash near the windshield is a sensor.

Check for good spring tension on the battery connections and make sure the switch isn't coming apart. I had the same problem with 2 different pumps and they both had both issues.
