If it was online, this would find it. You could try Sunbeam direct, we are Fixya, not them.

Does it have 1 or 2 elements?

Could be a problem with the thermostat control

Need to check the low voltage circuit for 24 volts, the 480 volt to 24 volt transformer may have a circuit protection reset or fuse installed. All the 3 phase electric heaters use a low voltage control circuit for operation of relays (24 volt coils).

If it is a problem with the controls they can be replaced.If it is a break in the internal wiring then you will need to get a new blanket. Thank you

you can get your parts at this web site.................www.grillstuff.com......scroll down to CHARMGLOW parts..enter your model # ...they will ship the part to you...I was just at that web site to verify.....GOOD LUCK..!!!

The switch itself is a (double pole single throw ) 15 amp 250 volt /20 amp 125 volt.You can buy any switch like that.The hard part is trying to find the same size to fit the hole in the heater.
