Warren for Model Number Whirlpool Estate TGDS840JQ1 Reading previous replies and comments here, I see there should be 3.2 to 3.6 VOLTS AC power at the gas valve when igniter is on....AND....the igniter should DRAW 3.2 to 3.6 AMPS current when igniter is on. Volts being read with volt ohm meter, and current being read with a clamp on amp probe. Is this correct? How does the 115 volts power supply to the dryer reduce to only 3.2 to 3.6 volts in the system?
Answer Hello Warren. That response is for a gas range, not a gas dryer. On the dryer, you will check the coils, and the flame sensor and thermal cut-outs. If all is good, then the igniter could be weak and need to be replaced in the unit. Check the coils 279834 and see if they test good. You can test the coils using a multi-meter MA-DM1. The two prong coil will read 1,000-1,300 ohms, and the three prong coil will read 1,300-1,400 ohms across prongs 1&2, and 500-600 ohms across prongs 1&3. Test the coils after running the dryer for about 10 minutes. Here is a link on how to use a multi-meter. http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html Read More...
