(3)For replacement of new
(4)Reestablish electrical service to the dryer.
3)Burner Fan Electrical Components
a)Burner Fan Thermal Magnetic Starter (TMS)
The thermal magnet starter (TMS) is used as a safety device to manually disconnect the motor so that it will be protected from damage in the event of a locked rotor condition. The overload has a dial setting on the face of the device. To set the overload, refer to the specific electrical diagram. The overload is specifically designed for motor applications. It has a current curve built into it so the initial high current draw by the motor will not trip the overload. On the face of the overload are two (2)
(1)Thermal Magnetic Starter (TMS) Replacement
(a)Discontinue electrical service to the dryer.
(b)Mark L1, L2, L3, and T1, T2, T3 on the wires to the TMS for correct replacements.
(c)Set the amp (amphere) rating on the TMS according to the electrical schematic supplied with the dryer.
(d)To remove the thermal magnetic starter (TMS), pull the tab on the bottom of the TMS and lift upwards.
(e)To install the new thermal magnetic starter (TMS), reverse Step d thru Step b.
(f)Reestablish electrical service to the dryer.
(2)Auxiliary Contact Block
The auxiliary contact block is mounted on the side of the overload. Its function is to sense an overload trip, thereby triggering a safety fault which will disable the drying cycle.
(a)Auxiliary Contact Block Replacement
(1)Discontinue electrical service to the dryer.
(2)Remove the thermal magnetic starter (TMS) from the din rail by pulling the tab on the bottom of the auxiliary contact block and lift upwards.
(3)Remove the two (2) wires going to the auxiliary contact block and label them for correct reinstallation.
(4)There are two (2) types of auxiliary contact blocks...one type has a screw and the other type has a clip. In either type, disassembly and assembly is recommended with the thermal magnetic starter (TMS) in the stop position.
