The short version
A dryer that tumbles without heat has usually lost the supply to its heat source rather than the heat source itself, and on an electric machine that often means half its power. The order below starts with supply, then goes to the safety devices, then to the element or burner. On an F&P dryer the place to start is the thermostats, because the moisture-sensing and control chain decides when this dryer stops, so it outranks the heater on the list.
What the machine is doing
- On a gas machine, no click or no flame at the start — The ignition sequence is not completing, which is a different chain from the electric one.
- The drum turns normally and the air stays cold — Everything mechanical is working and only the heat is missing, which narrows the list immediately.
- Clothes come out damp and cool after a full cycle — Same fault with the evidence at the end rather than during.
- NEAR MISS: it heats but the laundry is still damp — That is a cycle or airflow fault.
The causes, ranked for this brand
- An open cycling thermostat or high-limit — The thermostats decide when the element runs. Ranked first on an F&P dryer: this platform sits behind a sensing layer that decides what the machine may do next, so what the sensors believe explains the symptom far more often than a failed part does.
- A blown thermal fuse after a vent restriction — When the vent blocks, the machine overheats and a one-shot thermal fuse opens to protect it. Where it sits here: very common, and the reason nobody should fit a fuse without clearing the duct that opened the last one.
- A failed heating element, igniter, flame sensor or gas valve — On an electric machine the element is a coil that eventually breaks. Where it sits here: the genuine component failure of the set, and the only reason it is not first is that supply and fuse faults outnumber it.
- An air-fluff or no-heat cycle selected — Every dryer has a no-heat setting and it is one click from the ones people use. Where it sits here: trivial, free, and worth ten seconds before anything else is considered.
What to check first, and why that order
- Start at the thermostats — It is the cause that ranks first on this kind of machine, so it is the check that ends the diagnosis most often and the one that costs least to make.
- Check the cycle selected and the temperature setting — Ten seconds and it removes the most embarrassing possible outcome of a service visit.
- Check both breaker legs or the gas shut-off — On an electric machine switch the double breaker fully off and on again.
The checks you can make yourself
- Reset both breaker legs — Switch the double breaker fully off, wait, and switch it firmly back on.
About 10 min
- Clear the vent run completely — Brush the duct end to end and confirm the outside flap opens.
Tools: vent brush, screwdriverAbout 45 min
- Select a high-heat cycle deliberately — Set the machine to a cotton or high-heat programme rather than air-fluff, and run it for a few minutes with a hand at the vent.
About 10 min
- STOP HERE before testing fuses, thermostats or elements — All of those are meter checks on a dismantled machine, and on a gas dryer the burner assembly is not an owner area at all.
Before you touch it
Safety
Unplug the dryer or switch off its breaker before removing any panel; a capacitor can hold a charge after the power is off. Never bypass a thermal fuse or a high-limit thermostat to restore heat: those devices open because the machine was overheating, and defeating one turns a lint problem into a fire. On a gas machine, if you smell gas: do not switch anything on or off, leave the building and call the gas utility or emergency services from outside. Do not look for the leak yourself.
Where the owner job ends
Call once the supply, the cycle and the vent are all proven good and the machine still runs cold. Everything left on the list is behind a panel and is tested with a meter, and on a gas machine the burner train is licensed work. Call immediately if the machine has smelled hot or scorched at any point.

What is deliberately not here
This page covers F&P dryers as a class, not one family or model line. Where a family- or model-specific page exists for your unit, that is the more specific answer and the one to read first. Deliberately not here: element ratings, fuse and thermostat part numbers and the burner assembly references, all of which differ by family.
