The dryer runs but no heat!!:
First, I would make sure this dryer is getting 220 volts. Check the circuit breaker, check the wall socket, check the terminal block inside the dryer. Then, I’d check the heating element, thermistor and thermal fuse for continuity with an ohmmeter. Do not assume the heating element is bad just because it’s not turning on.
The heater element and fuses was tested and are good, what can I try next?
If your dryer has a element just below the lid, check the overload thermostat above it, common failure item. If ok check the timer contacts per the schematic.
