Victor for Model Number 417.80042990 Dryer heating but not very hot. Checked and cleaned entire vent system. Dryer must run 2 full cycles to dry clothes. Checked the thermal limiter inside of back of dryer. it is good. Checked the safety thermostat. it is good. Element does heat some what so it is probably good. Checked thermistor on blower housing. Got 10K ohms at about 70 degrees. What else could be wrong? Also tried the drier on timed and dryness settings with same heat issue.
Answer Hi Victor. The cycling thermostat mounted on the front of the blower controls the on/off cycling the temperature of the element. If It is not operating normally, it will effect the heating. It should read closed and the inner (smaller) resister terminals read approx. 10 K ohms at room temperature. If it is the thermistor type, it should read 50 K ohms at 77 °. The cycling thermostat is part # 134048800. The heater should ohm out to 12 ohms. If is is been restricted air flow the element will expand and contract enough to partially short out during heat. This can be an issue to observe as well. You will see a very black out area where the element has touched the case momentarily. The heater element is part # 131553900. Thank You. Read More...
