Question about Lakewood Oil-Filled Electric Radiator Heater
I have had this Lakewood heater for a number of years. Recently it just stopped heating eventhough I had not turned it off or adjusted the setting. How can I determine what has stopped working?
Use a multimeter set to Ohms, then check for continuity from the Phase to the switch, then to the Thermal fuse, < thats a good candidate for replacement, it should read a "Short" across it, OPEN circuit means it has failed. then from Thermal fuse, if OK, to Element(s), these should have resistance of about 12 - 15 Ohms...from one side to the neutral. When ON, there should be a Resistance reading on the Meter, of up to 20 Ohms measured across the 3 pin plug.would be OK.
Essentially with Neutral, as common, the Phase comes in to one side of a switch, the "Other" side of the switch goes to the Thermal Fuse, the "Other" side of that Fuse, goes to the "Hot" side of the Element. and the "Other" "Cold" side goes to Neutral, common. So essentially with the switch in the ON position, we should get a resistance reading on our meter. The reading is in accordance with Ohms law. IE: To get the resistance of an appliance, we take the Wattage, & divide it by the Voltage, Taking the answer from that, we then, divide the Voltage by that result, and we have our resistance. EG: 1000 Watts, divided by 112Volts = 8.9Amps. Therefore 112Volts divided by 8.9 = 12.4 Ohms. That is your resistance or Load. Hope this helps.
