2. Check whether the fuse tube of the main engine is broken. If the fuse tube is broken, it needs to be replaced; Otherwise, check the parameter setting of the temperature control meter. If the opt indicator light of the temperature control meter is on and the output signal light of the solid-state relay is also on, check whether the contactor is closed and whether the alarm relay works normally; If everything is normal, use a multimeter to measure whether the heating resistance of the host is normal.
