5.7FUSES

A.RM7030 (Product No. 921890201 & 921890301) The fuse is to protect the circuit board. To check the fuse, remove it from the holder and do a continuity check. If no continuity, replace it with a proper 3-amp time delay fuse.

B.RM7030 (Product No. 921890401) and RM7732 The fuses are to protect the circuit board and the integrity of the heater circuit(s) against shorts.

The 3-amp DC fuse is designed to protect the circuit board from internal shorts. The 5-amp AC fuse is designed to protect the integrity of the AC heater circuit from shorts.

To check the fuses, remove from the holder and do a continuity check. If no continuity, replace with a proper amperage fuse.

NOTE: Determine the cause of the fuse failure and correct before replacing fuse.
