if this component was CRIMPED IN POSITION and looks like a small metal canister this is possibly the thermal fuse usually rated for voltage ,current, and temperature
take the old one to maplins .tandys or R.S all of these 3 specialize in electronic components
re crimp new one in position do not solder due to thermal conductivity (heat will travel up the wire melting/blowing the fuse wire,) unless you know how to use a heat sink to conduct excess heat away
