115 VAC heater jacket is not heating Check the resistance between the black and white wires (tied together) and the blue wire. A 200 watt heater @ 115 VAC will draw about 2 amps so the resistance is around 61 ohms. If the measure is open for heater resistance the fusible link has blown and the jacket should be replaced.
230 VAC heater jacket is not heating Check the resistance between the black and white power wires using an ohmmeter. A 200 watt heater @ 230 VAC will draw about 1 amp so the resistance is around 245 ohms. If the measure is open for heater resistance, the fusible link has blown and the jacket should be replaced.
