Kill the power at the socket for a full five minutes, restart on a short program, and feel the air at the door in the opening minutes. Note the model number from the sticker inside the door frame while you are there; on this complaint it decides everything that follows. ### Why we clear before we test Thermal cut-outs exist to stop a dryer becoming a fire, and they do their job. What they do not do is explain themselves: the machine simply stops heating. Replacing a cut-out on a blocked machine gets you one more warm cycle and the same failure. So the sequence on this complaint is always clear the air path, then reset, then measure — and where the machine was genuinely clean, the measurement means something. ### The one place the platform changes the answer On a condenser machine an element, a thermostat and a cut-out are a modest repair. On a heat pump machine there is no element: heat comes from a refrigeration circuit, and if that has failed the arithmetic against the value of the machine changes completely. We say which case yours is at the diagnostic, with the figure, before anything is ordered. A thermal cut-out has tripped The machine protected itself against overheating caused by a blocked air path, and it will keep doing it until the path is cleared. Resetting without clearing achieves nothing. The heating element or a thermostat has failed On condenser machines, an ordinary repair with ordinary parts. Measured in circuit rather than swapped, because a thermostat reading wrongly makes a good element look dead. The heat pump circuit has failed On the heat pump platform this is the expensive answer, and it is only reached after everything ordinary has been eliminated. A compressor is not an element. Is the air at the door warm at all? Slightly warm and slightly warm are different from stone cold. Feel it in the first two minutes rather than at the end. Has it been overheating or smelling hot? A machine that has been running hot and now runs cold has almost certainly tripped its protection, and the cause is the air path. What is the model number? Inside the door frame. Heat pump or condenser is the difference between a part and a sealed system, and it cannot be told from the outside. The drum turns, the cycle runs, nothing gets warm What it usually means A blocked machine overheats, trips its cut-out and then runs cold Heat pump and condenser machines fail differently and cost differently Clear the filters first — a tripped cut-out with a clean machine is a real repair What to do in the next ten minutes Do the three filters properly — door lint, condenser washed clear, container emptied. Kill the power at the socket for a full five minutes, restart on a short program, and feel the air at the door in the opening minutes.

It will tumble and it will not dry, and if a cut-out has tripped there is a reason it tripped. Better to leave it until the air path is cleared. ### It heats for ten minutes and then stops. Classic overheating pattern — it reaches its limit and cuts out, then recovers as it cools. That is the air path almost every time. --- **[Read full article: Dryer runs but there is no heat](https://askomiami.support/symptoms/dryer-no-heat/)**
