VERMONTSTER, PLEASE READ THIS. ALSO OTHERS WITH unworking FAN MOTORS.
A fan motor is not bad until it has been connected direct to the wall power & still refuses to run.
Instructions how to hook your fan motor direct to the wall power,thus bypassing all control switches in the stove that might/could/maybe bad and any bad wiring connections that may or may not exist.
First I will say that i am not an expert on the lopi leyden, I dont own one & never even saw one, but i do know a little about electricity & wiring from running a major appliance repair shop for 20 years.
Therefore, first, unplug your stove for safety & look with a good flashlight & magnifing glasses or reading glasses to see if your fan motor is rated for 120 volts ac (vac)
& if it is ,disconnect the two wires leading to the fan motor & tape the female terminals at the end of the wiring harness that you just removed from the fan motor.
Take a 120 vac lamp cord & install on the end of its two wires the same type of terminals that were used to connect the original wires that you removed.
Now ,you can plug the fan motor inquestion into the wall socket or an extrnsion cord to see if it runs. If it does run, then the motor is ok & a switch or reostate somewheres else is at fault.
When I do this, I like to make up a line cord with a off/on switch with a duplex recepticle, so that I can plug in the test wire to the motor into the recepticle with the power off & just snap the switch to on ,to see if the motor will run. If you see sparks or smoke or hear funny noises from the motor,you can snap the switch off a lot faster than you can unplug a cord from the wall or an extension cord.
If the motor runs ok ,you can run it at full speed, without a reostat to get the disbursial of heat that you need from the fan motor. it will be ok until a repairman comes.
If you are the worry wart type you can put a 5 amp or 10 amp fuse in series with the switch that supplies the receptical trhat your fan motor is plugged into.
You must use a 3 prong plug on both the test cord & the switch & fuse cord so that the polatities of the stove & the polarities of the independent fan motor circuit remain the same
in regards to each other.
The motor shouls have a full load amperage rating stamped into the sheet metal of the motor or on a sticky lable on the motor. This is the same place where you looked to see the 120 vac rating. the amperage rating will then you what size fuse to put in the switchable cord.
amps or just (A)
