The short answer
No heat on the Costway GDZ dryer family splits into three questions asked in order: is air actually moving through the machine, has a thermal device opened, and is the element or the heat circuit itself dead. Answering them in that order costs nothing and stops you fitting a part to fix a blocked duct.
What you see on the GDZ family
- The drum turns for a full cycle and the load is still damp — The machine is running perfectly and producing no heat, which is the defining case for this page.
- The load is damp and the machine feels hot to the touch — Heat is being made and is not leaving, which is the airflow case rather than the element case.
- Cycles that used to finish now take much longer — A gradually restricting exhaust shows up as time before it shows up as no heat at all.
- A hot or scorched smell around the machine — Lint accumulated where heat has to escape. Stop the machine and clear it before running anything else.
Causes, most likely first on the GDZ family
- Restricted exhaust, lint filter or duct — Ranked first on the GDZ family — it is the most common cause of no heat on the Costway GDZ dryer family and the one that causes the other causes. Lint collects in the filter housing, in the duct behind the machine and at the outlet, and a dryer that cannot exhaust cannot dry. The heat then builds inside the cabinet until a thermal device intervenes.
- Thermal fuse or thermal cut-out opened — Second — and inseparable from the first: the fuse opens because the airflow failed, so clearing the vent is part of the repair. A one-shot thermal fuse opens permanently after an overheat and kills the heat circuit, leaving a machine that tumbles cold.
- Heating element or the heat circuit — Third — less common than airflow and always worth checking after the vent rather than before it. An element that has burned through makes no heat while everything else runs normally. On a machine fed by two legs, losing one leg leaves tumbling without heat and is a supply fault wearing an element costume.
- Thermostat, control board or a moisture sensor misreading — Fourth — and the one to consider once the vent, the fuse and the element are all accounted for. A cycling thermostat that has failed open never calls for heat. A moisture sensor reading a dry load ends the cycle early, which feels like no heat but is really no time.
- Body: The order below is this family's rather than the brand's: with one build in the GDZ family the ranking is not an average diluted by chassis that fail differently, so the cause at the top is the cause that actually leads on GDZ60-608E.
Check in this order, and why
- 1. Pull the lint filter and look at the housing behind it — Clean the screen and check the cavity underneath, because a filter that looks clear can sit above a packed housing.
- 2. Disconnect the exhaust and run the machine briefly — If it heats with the duct off, the duct is the fault.
- 3. Feel the cabinet and the load after a short run — Hot cabinet with a damp load is airflow; cool cabinet with a damp load points at the heat circuit.
- Body: Because the GDZ family is one model, the access route below is the access route — there is no second layout to hedge against, which is exactly what the page above this one has to do.
Before you open anything
Safety
Unplug the appliance or switch off its breaker before removing any panel — a capacitor can hold a charge after the power is off. Lint is fuel: a machine that smells hot should be stopped and cleared rather than run again to confirm the symptom. Never run a dryer with the exhaust disconnected for longer than the few seconds a test needs, and never bypass a thermal fuse to get a cycle finished.

When to call a technician
On the Costway GDZ dryer family the owner line is the lint path. Filter, housing, duct and outlet are yours; the thermal devices, the element and the wiring to them are not. A machine that has opened a thermal fuse more than once has an airflow problem nobody has found yet, and that needs a technician rather than another fuse.
