The Sunbeam SLP3310 electric heater won't stay on, goes on then shuts off right away.

Was having same problem, found the fan needed a little oil on bearings. Was not spinning up to full speed so heater was cylcing on high limit

Did the burners light and then shut down right away?

If you have the same heater i do then in between the elements at the bottom there is a safety swith that bends when it heats up and breaks the connection Dont mess with it plugged in it will shock the hell out of you but if you bend it down it wont be able to lift off the circut and will stay running untill you turn it off

You won't get heat right away. The heat has to have time to reach the heater core. That's where you get the heat for the passenger compartment. But if the fan isn't turning off, then I would have it checked for an electrical problem.

Coil spring is burnt Cheeper to buy a new one

Which model Sunbeam mattress pad do you have? Sunbeam has some of their manuals here: http://www.sunbeam.com/manuals.aspx . The electric bedding share a manual. The direct link is http://www.sunbeam.com/BeddingManuals/SunbeamBedding/Universal.pdf .Make sure that you are using the master control for your side of the bed (that's the one closest to the plug for the wall outlet).

You may need to turn on the second control and set it to 0 at night. If you still are having a problem with the heat being uneven, you might need a replacement mattress pad. I know we've replaced several electric blankets or mattress pads due to problems with the control/uneven heat.

I hope this helps.

Are you getting any hot water from taps? If not, check by-pass valve on back for proper positioning. You want cold going in bottom fitting open, as well as hot coming from top fitting open too. Any valves etc., in between should be closed. Let me know what happens please.

It's broken --- call Sunbeam customer service (888) 264-9669 and have your receipt and serial number ready. They are aware that these have faulty switches in them.
