Frigidaire gas dryer. 7 Years old, out of warranty. Gas valve opens in cycle (low flow), ignitor glows nice and red, starts flame, high flow gas opens, dryer starts to dry. During some (not all) cycles, gas valves cycling at very high rate - clickety-clack, clickety-clack. Flame sensor was good (continuity), but replaced anyway. Coils suspect, but within range, repalced anyway. Gas valves operate freely (no binding). What else is there? The random nature of excessive gas valve opening/closing suggests something other than a continuity device issue, but not sure where to go from here. Any help?
Answer David, Based on your post, you'll need to start looking at the heater relay on the control board 134523200 or the motor switch 131560100, The heater relay supplies voltage to the valve(through the thermistor and hi limit thermostat) and the motor switch completes the circuit to netral. If there is a loose wire connection or the relay or motor switch has a weak contact , the gas valve can Short cycle and make a chattering or clacking noise. Good Luck and Thanks
The dryer gets way to hot, we checked all the lint traps, the outside lint thing, and nothing is blocked, it melts delicate fabric. We have it on the lowest heat setting and it gets so hot sometimes the cloths are to hot to touch. It has ruined almost all of our clothes. I need to know what part we would need to replace to make it dry right? PLEASE if anyone can help , I just am at my whits end, I cant afford to buy new clothes! Thank you guys! Oh yea someone told me to get a cycle thermostat, and I looked here and it doesnt say it has one, it says stfty thermostat? Is that the same thing? thank you everyone!
Answer Dana, The safety thermostat is not likely the issue,at this point. It's rated at 180 dgs.F. and usually causes the dryer to run longer than expected and the clothes are damp in most cases. If you want to try a new thermostat consider the regulating thermostat 131298400 or temperature selector switch 134398500 . But the ideal situation would be to check the exhaust temperature, with the venting disconnected from the dryer, with a "cooks pocket thermometer" and check for an average temperature of 150 to 160 dgs.F. on the high temperature setting. Good Luck and Thanks
I have checked all four connections for continuity and they test fine. cleaned everything out of lint even took the drum out and cleaned behind the airvents back there. Dryer spins and is getting gas from the wall to it (we cracked the line and smelled the gas) but it does not heat up while rotating? any ideas? is there something on the gas that needs to ignite to light the flame?
Answer Dan, There are several components involved to release and ignite the burner. The igniter 5303937186 it must be in tact and glow in order to ignite.The radiant flame sensor 5303281135 has to be a closed circuit for the igniter to glow, and an open circuit when the igniter is hot enough to ignite the gas. You may want to remove the louvred inspection panel on the back and observe the ignition process, so we know what and what does not occur, so we can better assist you. Thanks and Good Luck
How do you test the safty Thermostat?
Answer Hello Pat. You can test the safety thermostat 5308015399 for continuity. It should read closed. You can test this with a multi-meter TJMA-DMT3. Here is a link on how to use a multi-meter. Hope this helps. http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html
How do I test the coil that opens up the gas valve for the heat to work in the dryer?
Answer Hello Dan. To check the coils 279834 and see if they test good, you can test the coils using a multi-meter TJMA-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. Run the dryer for about 10 minutes and then test the coils. Here is a link on how to use a multi-meter.
