Hotpoint Dryer Not Heating? Here’s What to Check First

A dryer that runs but doesn’t produce heat is one of the more frustrating appliance problems. Your laundry tumbles for an hour and comes out just as wet as it went in. The good news is that a Hotpoint dryer that isn’t heating almost always comes down to a small number of components, and several can be diagnosed and replaced yourself.

This guide walks through the most common causes in order, starting with the simplest. Before doing anything else, make sure the dryer is unplugged before accessing internal components.

Check the Basics First

Before opening anything up, run through a few quick checks that sometimes solve the problem immediately.

First, if your Hotpoint dryer is electric, check the circuit breaker. Electric dryers run on two 240 volt legs of power, and it is possible for one leg to trip while the other remains on. When this happens, the drum still turns but the heating element does not get power. Go to your breaker panel, find the dryer breaker, and reset it fully by switching it off and then back on.

Second, check the exhaust vent. A blocked or kinked vent hose causes heat to build up inside the dryer, which can trigger the safety system and shut off heating. Disconnect the vent hose from the back of the dryer and run a cycle. If heat returns, the vent system needs to be cleaned or replaced.

1. Thermal Fuse

The thermal fuse is the most common cause of a Hotpoint dryer not heating and the first component to test. This small fuse is a one time safety device designed to blow if the dryer overheats, cutting power to the heating circuit. Once it blows, it cannot be reset and must be replaced.

The fuse is typically located on the exhaust duct inside the cabinet, near the heating element. On most models, accessing it requires removing the back panel. With the dryer unplugged, locate the fuse, disconnect the wires, and test it with a multimeter set to continuity mode. If there is no continuity, the fuse has blown.

Thermal fuses are inexpensive and the repair is straightforward. If the fuse has blown, there is usually an underlying cause. A clogged exhaust vent is the most common, so clean the vent system before running the dryer again.

2. Heating Element

In electric Hotpoint dryers, the heating element generates heat. It is a coil of resistance wire housed inside a metal frame, and it heats up when electricity passes through it. Over time, the coil can break or burn out, which prevents it from heating.

To test the heating element, access it through the back panel with the dryer unplugged. Visually inspect the coil for breaks or burn marks. Then test it with a multimeter. It should show continuity across the terminals. If there is no continuity, the element has failed.

Heating elements are widely available and the replacement is a manageable DIY repair.

3. High Limit Thermostat

The high limit thermostat is a safety component that monitors air temperature inside the dryer and cuts power to the heating element if it gets too hot. Unlike the thermal fuse, it is designed to reset, but it can fail in the open position. When that happens, it prevents the heating element from turning on.

The high limit thermostat is usually located on or near the heating element housing. Test it for continuity with a multimeter. It should show continuity at room temperature. If there is no continuity, it has failed and needs to be replaced.

This is another inexpensive part that is relatively straightforward to replace.

4. Cycling Thermostat

The cycling thermostat regulates the dryer’s operating temperature during a normal cycle. It cycles the heating element on and off to maintain a consistent heat level.

When it fails, it can either cause overheating or prevent the heating element from turning on at all. If it fails in the open position, the dryer will not heat.

Test it with a multimeter for continuity. A failed thermostat will show no continuity and should be replaced.

5. Gas Valve Solenoids (Gas Dryers)

If you have a gas Hotpoint dryer, the heating system works differently. Gas dryers use a burner assembly, and gas flow is controlled by a set of solenoid valves. When these solenoids fail, the gas valve does not open and no heat is produced.

A common symptom is a dryer that heats briefly at the start of a cycle, then goes cold. The igniter lights the gas, but the solenoids cannot keep the valve open.

Solenoids are sold as a set and are one of the more common gas dryer repairs. If the igniter glows but heat does not continue, the solenoids are the likely cause.

6. Igniter (Gas Dryers)

On gas dryers, the igniter lights the gas coming from the burner valve. It heats to a high temperature to ignite the gas and create the flame. Igniters are made of a brittle material and can fail over time.

To check the igniter, observe it during a cycle with the front panel removed. Use caution when doing this. The igniter should glow bright orange within the first minute.

If it glows but does not ignite the gas, the solenoids are likely the issue. If it does not glow at all, the igniter has failed and needs to be replaced.

When to Call a Technician

If you have checked everything above and still cannot find the problem, or if you’re not comfortable testing parts, it might be best to call a technician (especially for issues with wiring/the control board which require professional tools and experience).

Before you attempt a repair, consider a few things:
