Shane for Model Number DV48H7400EW/A2-0000 Dryer not heating: I have checked input voltage and relay voltage, as well as continuity of thermostat, heater and the thermal fuse on the blower housing. I replaced the thermal fuse on the duct housing (the one mounted on the bracket) and that corrected the issue for ~half a load of laundry. After that load the same issue re-occurred. I just took the dryer back apart to check the continuity of the replaced thermal fuse and it had again been tripped and measured no continuity. I have checked the entire flow path and it is unobstructed, I am very diligent in cleaning the lint screen before every load and there is plenty of air flow coming out of duct outside of house. My question is what is causing the thermal fuse on the duct housing to fail this quickly? Is this an indicator that my control board needs to be replaced? I have read other posts saying that this is a common failure on this model, but I would like to have some sort of affirmation prior to spending ~$90 on a new control board. Additionally is there anything I can check (ohm-meter or otherwise) on the control board to see if there is some sort of fault present? Thanks in advance for any assistance that can be provided.
Answer Shane, This issue would likely be caused by the relay for the heater sticking on the control board causing the thermal fuse to blow. This would require a new control board. Read More... Answered by AppliancePartsPros.com | Monday, December 5, 2016
