Have a model 2150 heated mattress pad, one year old, with dual controls. One control is blinking and won't heat up the pad. I have unplugged twice and checked the plugs into the pad itself,

First, I am not familiar with your particular Pad. But they all work in a similar fashion. Second... you would be wiser taking your pad to an electrician if you are not competent with electricity. (Especially 240V AC where I am.)
If it's only 120v AC then the sting is not as bad. I've had Both!
The Pad is not worth your life.
That said....
Obviously the AC power is OFF & disconnected first.
Use a multimeter in Ohms or Beeper Mode to look for an open circuit in the element(s) inside the blanket.
If the pad connector comes to the edge somewhere then this is where to test the pins. No AC Power Needed.
On Ohms mode it should show some small resistance in the element. Thats why it heats up....
If the element is internally broken (open circuit) then I doubt it can be repaired.
A multimeter can be a useful tool in a modern house these days.
They can be picked up pretty cheap now. $10 to $50.
The probes can check for AC & DC voltages.
The current function would never be used by the average person.
The Beeper Test uses the internal battery for open & closed circuit testing. The Ohms function will show the resistance of elements and the like.
If you are unsure how to use one then ask the supplier or an electrician / technician to show you.

Why has my heated mattress pad stopped working?

Electronics fail. Sounds like the digital controller has failed. A Google search finds others with the same problem. Biddeford models come with a 5-year warranty, so if yours is less than 5 years old, I suggest you contact Biddeford by telephone: 800.789.6441 or visit their website:

Electric blanket won't heat

Take the help of your mattress pad company or look into instruction manual. Do not operate it unless you are familiar with it. You should call the customer care to know how to operate.

Mattress pad not heating up

There must be a problem with wiring. You must contact with the manufacturing company or some electrician to go through the control box. Do not try to deal with it by yourself as it may cause damage.

I need instructions on operating a remote to Sunbeam,Cal-King, electric mattress pad.

Which model Sunbeam mattress pad do you have? Sunbeam has some of their manuals here: . The electric bedding share a manual. The direct link is .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.
