Understanding the Problem
Overview: The Kenmore 110.72332512 is a common Whirlpool‑based gas/electric household dryer platform. Typical problems are: dryer won’t start, dryer runs but won’t heat, drum won’t turn, long drying times, and loud unusual noises. Below are practical diagnostic and repair steps for each major symptom — start with the simplest checks and progress to component tests. 1) Dryer won’t start / no power 1. Verify power: electric dryers require 240V (two hot legs). Check the circuit breaker(s) in your panel; reset any tripped breakers. For gas dryers check the 120V circuit. Confirm outlet is live using a multimeter. 2. Check door switch: open door, press switch manually — dryer should not run when open. With dryer unplugged, remove door switch and test for continuity with a multimeter; replace if open when closed. 3. Test start switch and timer/controls: with power off, test start switch for continuity when pressed. If faulty, replace switch or control board as needed. 4. Thermal fuse / safety cutouts: a blown thermal fuse can prevent startup on some models. Locate the thermal fuse (on blower housing or near the exhaust duct). With power off, test for continuity; replace if open. 5. Drive motor or belt: if you hear a humming but no drum spin, the motor may be seized or the belt broken. Remove front or rear panel to inspect belt and motor. Replace broken belt or motor as required. 2) Dryer runs but won’t heat (electric) 1. Check venting and lint screen: restricted venting causes poor/no heating. Clean lint screen, lint trap housing, and the vent duct to the outside. Run dryer and feel exhaust; weak airflow indicates blockage. 2. Thermal fuse: this is the most common cause of no heat. With power off, test thermal fuse for continuity; replace if open. 3. Heating element assembly: visually inspect for broken coils. Test element coils with a multimeter for continuity; replace assembly if open. 4. High‑limit thermostat / cycling thermostat: test thermostats for continuity; replace if defective. 5. Wiring and power supply: verify 240V supply (for electric) at the terminal block and inspect for burned connections. 3) Dryer runs but won’t heat (gas) 1. Confirm gas supply and valve: ensure gas supply is on. You should hear or sense a click when igniter engages. 2. Igniter: if igniter doesn’t glow, test igniter continuity and replace if broken. 3. Flame sensor/thermocouple and gas valve coils: if igniter glows but no flame, test coils and gas valve operation; replace faulty coils or the gas valve assembly. 4. Thermal fuse and thermostats: same checks as electric regarding safety cutouts. 4) Drum won’t turn / won’t tumble 1. Inspect drive belt: remove access panel and look for a snapped or slipped belt. Replace belt if worn or broken. 2. Idler pulley and tensioner: check idler for seizure or excessive play; replace if noisy or not turning freely. 3. Drum rollers / bearings / glides: worn rollers or glides cause dragging and prevent rotation. Remove drum and inspect/replace as needed. 4. Drive motor: if motor does not run or hums and stalls, test motor for continuity and replace if failed. 5) Loud noise, squeal, or rumble 1. Determine noise source: run dryer empty and listen closely (outside may help). Identify front/back where noise is loudest. 2. Drum rollers or bearings: squeal/scrape indicates worn rollers or bearings. Replace rollers, shafts or rear bearing as required. 3. Idler pulley or motor: squeal during spin often means idler or motor bearings are bad. Replace defective part. 4. Foreign objects: coins or hardware in drum or blower housing make loud noise — inspect and remove. 6) Long dry times or clothes still damp 1. Clean vent system: remove lint and inspect entire exhaust run for restrictions or kinks; clean or replace ducting if needed. 2. Moisture sensor: if installed, clean sensor bars inside the drum (residue can interfere). Test sensor and replace if not detecting moisture correctly. 3. Heating and thermostats: ensure heating element and thermostats are working properly (see heating checks above). Basic replacement steps (applies to most internal parts: thermal fuse, heating element, belt, rollers) 1. Unplug dryer (and turn off gas if gas dryer) and move dryer away from wall. 2. Remove front or rear access panel per model: typically remove screws along the back or front and lift off panel. 3. For thermal fuse and thermostats: locate on blower housing or duct; disconnect wires (note colors/position), remove fasteners and install the new part. Reconnect wires exactly. 4. For heating element: remove housing screws, disconnect element wiring, pull out element assembly and replace. Re‑route element per service manual to avoid pinching. 5. For belt/idler/rollers: release tension from idler, remove old belt and hardware, install new rollers and belt routing, verify drum rotates freely before reassembly. 6. Reassemble panels, restore power (and gas), and test dryer on an empty load. Safety note: Always unplug the dryer and shut off gas (for gas models) before working on the appliance. Use a multimeter rated for household voltages and take photos or label connectors before disconnecting to ensure correct reassembly. If you’re not comfortable working with gas or high voltage (240V), hire a qualified technician.
Common Symptoms
No power or won't start; runs but clothes remain damp/no heat; drum won’t turn; loud squealing or rumbling; long dry times.
Common Causes
- Blown thermal fuse or failed safety thermostat
- Clogged venting or lint trap restricting airflow
- Failed heating element (electric) or igniter/gas valve (gas)
- Broken drive belt, seized idler/motor, or worn drum rollers

Helpful Repair Tip
Thermal fuse is the single most common cause of 'no heat' and 'no start' on these models — with the dryer unplugged, test the thermal fuse for continuity first; if it's open, replacing it often restores operation (but always clear venting before replacing to prevent repeat failure).
Frequently Asked Questions
How do I tell if the thermal fuse is bad?
Unplug the dryer and locate the thermal fuse on the blower housing or near the exhaust duct. Remove the wires and test with a multimeter for continuity — a good fuse shows continuity (close to zero ohms); an open reading means the fuse is blown and must be replaced. Note: replace the fuse only after fixing the cause (usually blocked venting) or it will blow again.
Can I clean a clogged vent myself or should I hire someone?
You can often clean the lint screen, lint trap opening and the first few feet of duct yourself using a vacuum or vent cleaning brush. For long runs, roof or wall caps, or if you suspect a major blockage, hire a professional vent cleaning service — restricted vents reduce dryer performance and are a serious fire hazard.
