Product review (4 stars): Good Replacement Part... Terminal Connector Faults
I had asked a question about this heater coil replacement for my commercial dryer and this product works the same as my old heater coil.  "Commercial" only means it is coin operated and not an industrial type of heavy duty dryer.  Issues I had was that that my jumper wire from the high limit thermostat to a terminal of the heater coil was melting.  A terminal from the old heater coil had partially broke apart which caused the jumper wire to arc, heat up and melt due to high resistance.  I looked everywhere on the net regarding this issue and found similar events but no one came out and stated the bad terminals caused this.  Well .. I'm stating that this is the case.  I've also been looking for the component parts for the heater coil so I can replace the terminal but I can't find those parts anywhere; maybe where it is manufactured in China?  If the high limit thermostat is good and the thermal cut off fuse is good then check the terminals to heater coil.  Make sure the terminals; spade connectors are good and tight when connected with no defects like rust on it.  That jumper wire is available to order but you need to terminate the other side of that wire with 1/4" female spade connector (yellow). There is also a thermal air flow fuse for the exhaust too... if it was bad it would shut down the heater coil.  Other notes:  the (male) spade connector mounted on the heater coli is a 5/16 connector; you cannot get that from the local hardware stores or appliance part stores nor anywhere I can think of.  Another note is that you have to take the old high temperature thermostat (working one) off and mount that onto the new heater coil as that thermostat doesn't come with this heater coil.  Sorry about the long comment but I'm trying to be as accurate as possible and also helpful notes to consumers in case most of us are not that "handy" with repairs and this would eliminate guess work and wasted money.
