My dryer blows cold air . I made sure that the vent was clean ,I checked continuity with the fuse, which is good. The dryer is spinning and the timer is working. To add to info, 2 days ago i cleaned the blower and vent duct from lent, it wasn’t an excessive amount of lint and it started blowing hot air, now 2 days later it’s blowing cold air again, also I must add it is coin-op. i am interested in replacing all pats that would be related with in reason to make it a onetime blanket event since I have everything apart, to avoid having to open her back up to change another part.
Pretty simple: all of these parts have to be tested for continuity in the above sequence.
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
If any of them is open – it has to be replaced.
If the thermal fuse is blown – it has to be replaced together with the cycling thermostat.
[LEFT]Gas valve coils also could be tested by resistance. There are two coils – one with three terminals and one with two terminals. 1. Coil with two terminals should have 1220 ± 50 Ohms 2. Coil with three terminals if held with terminals in upper position: a) across the left and the middle terminals – 1365 ± 25 Ohms b) across the left and the right terminals – 560 ± 25 Ohms[/LEFT]
