Our gas dryer (propane) will not heat. The dryer spins fine. There are no blockages on the exhaust. All appears to be working normally, just no heat. I saw your post for troubleshooting. (See Below) Do these still apply to our dryer?
[LEFT][COLOR=#000000]There are five major electrical parts involved in the heating process: [/COLOR][/LEFT]
[LEFT][COLOR=#000000]1. Thermal fuse[/COLOR]
[COLOR=#000000]2. Cycling thermostat[/COLOR]
[COLOR=#000000]3. Igniter[/COLOR]
[COLOR=#000000]4. Flame sensor[/COLOR]
[COLOR=#000000]5. Gas valve coils[/COLOR][/LEFT]
[LEFT][COLOR=#000000]How to find out which part causing the problem?[/COLOR][/LEFT]
[LEFT][COLOR=#000000]Pretty simple: all of these parts have to be tested for continuity in the above sequence.[/COLOR][/LEFT]
[LEFT][COLOR=#000000]The following article on our forum will explain in detail how to run a continuity test using either an analog meter or a digital meter - How To Check Continuity With Ohmmeter[/COLOR][/LEFT]
[LEFT][COLOR=#000000]If any of them is open – it has to be replaced.[/COLOR][/LEFT]
[LEFT][COLOR=#000000]If the thermal fuse is blown – it has to be replaced together with the cycling thermostat.[/COLOR][/LEFT]
[LEFT][COLOR=#000000]Gas valve coils also could be tested by resistance. There are two coils – one with three terminals and one with two terminals.[/COLOR]
[COLOR=#000000]1. Coil with two terminals should have 1220 ± 50 Ohms[/COLOR]
[COLOR=#000000]2. Coil with three terminals if held with terminals in upper position: [/COLOR]
[COLOR=#000000]a) across the left and the middle terminals – 1365 ± 25 Ohms[/COLOR]
[COLOR=#000000]b) across the left and the right terminals – 560 ± 25 Ohms[/COLOR][/LEFT]
[LEFT][COLOR=#000000]Thanks in advance for your help.[/COLOR]
