This accuracy isattained only if the thermostat bulb is placedproperly against the heat transfer tube. Toquickly and accurately test for proper bulbplacement and pressure a single thickness ofwriting paper should be pulled throughbetween the tube and the bulb with mediumresistance. If the bulb is too loose, the paper will slipthrough with little or no resistance. A fryerwith a thermostat bulb that is too tight willovershoot. If the bulb is too tight, the paper will eithernot pull through or it will tear. A fryer with athermostat bulb that is too tight will shortcycle.Thermostat Bulb PositioningREQUIRED TEST EQUIPMENT:Multimeter for testing continuityCHECKING CONTINUITY WITH THEMULTIMETER1.
