Daniel for Model Number Samsung Dryer DV42H5000GW/A3 The dryers takes hours to dry a load. I checked the venting and all is fine. I hired a repair technician and he said it is working fine and also checked the venting. I replaced the thermister, no change. The burner comes on for 2-5 seconds then drops out. It eventually relights but drops out 2-5 seconds later. The drum is warm but not hot like before. Could the thermal sensor be causing this?
Answer Daniel, Thanks for the question!!! The most common cause for what you are experiencing would be the gas valve coils (part number 279834) have failed. Test the coils for resistance with terminals facing you. For the coil with three terminals: The left terminal to the center measures 1365 ohms +/- 25, left terminal to the right terminal measures 560 ohms +/- 25. Then the coil with two terminals measures 1220 ohms +/-50. Replace both coils if one fails resistance testing. If the coils are good the valve DC62-00201A would be the next likely issue. However, you cannot test the valve for mechanical failure. Note: the valve includes new coils as an assembly. Read More... Answered by AppliancePartsPros.com | Friday, September 30, 2022
