Open circuit on electric heater

Well, it's a little late but since this is still up and people still read it apparently, here's a few more pointers on problems like this.

The part that blew is usually called a thermal fuse, and appliance parts stores usually insist on knowing the temperature that is printed on the side in order to get you a replacement.
They should also be able to sell you heat-resistant crimp-on connectors with which to install it.

Small motors usually slow down and stop because the bearings are plugged up with dust and crud. A drop or two of light oil might work but more likely you'll have to disassemble the motor. Don't use WD-40 unless you like your house full of that smell, and if you do chase it with some real oil because it evaporates out of the bearings and leaves them dry eventually. Be careful not to bend the fan blades. Clean the bearings and the shaft until a white piece of cloth doesn't show any dirt.

For those of you with heaters still running, an ounce of prevention: Take care of the motor as soon as you notice it running slow. The slower it runs the hotter the coils get and if they get hot enough the thermal fuse blows and you have to hassle with replacing it. Also, nichrome wire eventually fails by breaking, stretching, and/or sagging; and the hotter it gets the sooner it fails.

FUSEABLE LINKS ARE AVAILABLE AT ANY APPLIANCE STORE IN YOUR AREA MAKE SURE TO KNOW THE WATTAGE OF THE HEATER. SOME PART MANUFACTURES HAVE A "RESETABLE" LINK. TAKE THE HEATER WITH YOU TO THE APPLIANCE PARTS STORE. SORDERING IS BEST BUT RISKY BECAUSE OF THE HEAT. IF THE LEADS ARE LONG ENOUGH YOU CAN WRAP THE BODY OF THE FUSIBLE LINK WITH A WET TISSUE ... AND BE QUICK WITH THE SOLDERING.NEED I HAVE TO SAY TO DRY COMPLETELY? THE FAN IS SHOT THATS WHY THE LINK BLEW ... DID YOU REPLACE OR GET THE FAN RUNNING UP TO SPEED???
