I looked online before posting but couldn't find anything. I have a Samsung DV42H5000EW/A3 dryer that's not blowing any hot air. I already replaced the heating coil and the thermostat. The dryer starts up normally but no heat comes out of the dryer. I keep seeing that you can diagnose the dryer using error codes, but I'm not getting any error codes on startup. Also, how do you get the dryer into diagnostic mode?
Is it just holding the "dry level" and "temp" buttons and then pressing the power button?
When I do that the LCD screen just goes dark, nothing works until I press power again to turn the dryer off, then press power again to turn it back on.
But I'm not getting any codes.

Are the error codes something that appears when your first start the dryer?

Any help would be appreciated, thank you!

I'm not that familiar with Samsung Dryers so I don't know the answer to that, hopefully a Samsung tech. that works on this dryer "Day in and Day out" can answer that for you.

The first thing you want to check for when its running BUT NOT HEATING(ON ANY DRYER) is the dual breaker to the dryer in your house breaker box, if one is tripped and the other isn't that will make the dryer only get 120 volts to run the motor, but it needs 240 to make it heat.

One more thing,

I always check the voltage at the terminal block where your dryer power cord hooks up to first. Use a multimeter to check for 240 volts across the 2 outer terminals.

So pull the dryer out from the wall, then unplug it, then open the access panel where the power cord wires mount on the dryer terminal block, then see if you notice any burnt wires.

I see this happen a lot too:

If no burnt wires, then plug the dryer back in and put your meter leads on the two outer terminals and see If your getting 240 volts across the outer two terminals.

IF NOT--->That's the problem when the dryer runs but doesn't heat.

Ok. thanks for the help, ill keep this in mind for future problems as my dryer is about 8 years old.

I found out what the issue was. My new Thermal Fuse wasn't working. I tested it with an Ohm meter and it wasn't working. The new heating coil came with the thermostat and thermal fuse so we swapped everything out with the new parts while we had the dryer open. Get yourself an Ohm meter and test your parts first before installing. Here are the ones I bought.

Thermal Fuse:
DC96-00887C

Amazon is crap when it comes to getting parts from them IMO, they are aftermarket parts and half the time they don't work properly, if it all, from what you mentioned.:)

I removed your amazon link to that thermal fuse and put the OEM thermal fuse in its place. We are very much against getting any parts from amazon.

I only get OEM parts for my customers from AppliancePartsPros and RepairClinic BOTH companies Always has a 365 day warranty on ALL parts at no extra charge!

Glad you found that amazon thermal fuse was the problem with your meter.(y)
