Stopped working, no smell or anything just stopped working, replaced fuse, what is problem?
First, make sure heater is plugged into a working outlet on at least a 15-amp circuit. To test the outlet, plug a known-working lamp into it and see if you can turn it on.
Then, turn on both switches and turn up themostat (clockwise, as i recall) until you hear a faint click. If it starts working, then you just didn't have it set high enough. If it doesn't work, problem could be bad switches, bad thermostat, bad power cord and/or plug, and/or bad heating element.
Troubleshooting down to the individual component requires use of voltmeter or ohmmeter, and MUST BE DONE WITH THE UNIT UNPLUGGED!!!!!!!!!!!!!!!!!!!!!!!!!!!!
First, FOLLOW ALL SAFETY RULES AND SAFETY PRECAUTIONS AND COMMON SENSE when working on this unit. If you are in doubt or don't know what these rules and safety precautions are, DO NOT OPEN OR ATTEMPT TO REPAIR THIS UNIT!!!!!!!!!!!!!!!!!
To test each of the above components safely, first UNPLUG THE UNIT FROM THE OUTLET. Then, WITH THE HEATER UNPLUGGED, open up the heater and, with a DVM or other ohmmeter, measure the resistance across each switch, across the thermostat (with contacts closed), and across the heating element. Ohmmeter should read as 0 ohms across switch & thermostat contacts. Resistance of heating element should read less than about 25 ohms. Resistance of each conductor of power cord should read less than about 1 ohm. Replace defective parts ONLY with replacement parts purchased from the manufacturer, and install them and re-assemble the unit per manufacturer's original design and instructions. When finished, verify that there are no short circuits from the power cord to the heater frame, by unplugging the unit, turning on all switches and turning up the thermostat to maximum, and measuring the resistance from both prongs of the power cord touched together to one probe of the ohmmeter, to the frame of the heater. Set the ohmmeter on its highest-resistance range. You should not measure ANY continuity at all, which means resistance should measure infinity. If you measure anything less than infinity, do not use the heater. If you do not understand ALL OF the forgoing instructions or cannot carry out all of them, DO NOT ATTEMPT REPAIR OF THE HEATER!!! Again, SAFETY FIRST!!!! DON"T TAKE CHANCES! THIS UNIT CARRIES LETHAL VOLTAGES INSIDE. IF YOU'RE NOT ABSOLUTELY SURE YOU KNOW WHAT YOU'RE DOING, DON'T OPEN OR ATTEMPT TO REPAIR THIS UNIT!!!!!! Stay Safe!!!! Stay alive!!!!
And, make sure you unplug this unit when not in use or away from home!
Good luck, and STAY SAFE!!!!
