To change the belt on your Hotpoint gas dryer model HTDX100GM7WW, we remove the front/top to access the drum, release belt tension at the idler pulley, lift the drum out, then route a new belt around the drum and motor pulley before reassembling and test-running the dryer.

Before you start (safety and prep)

• Shut off the gas supply valve.
• Unplug the dryer (or switch off the breaker).
• Let the dryer cool completely.
• Work in a well-ventilated area.
• Take photos of the belt path and wire connections as you go.

Step-by-step belt replacement overview

1. Remove the lint screen, then remove the top panel fasteners and lift the top.
2. Remove the front panel (and disconnect the door switch harness if needed).
3. Reach under the drum and push the idler arm to relieve tension, then slip the belt off the motor pulley.
4. Use the old belt as a “handle” to lift the drum out of the cabinet.
5. Install the new belt around the drum (ribbed side against the drum).
6. Route the belt through the idler pulley and onto the motor pulley; rotate the drum by hand to confirm the belt tracks straight.
7. Reinstall the front panel and top, reconnect the door switch, then restore power and gas and run a short timed cycle.

What to inspect while you have it open

A worn belt often shows up with squealing, thumping, or a drum that stops turning. While the drum is out, we check these common wear parts:

• Drum support glides: dryer drum glide bearing, upper WE03X37320 and dryer drum glide bearing WE03X37319
• Belt tension parts: dryer idler pulley WE03X31620 and dryer idler pulley arm WE03X20434
• Rear drum support: dryer drum bearing bracket WE1M300 (and its O-ring if equipped)

Quick symptom-to-part guide

Symptom	Most common cause	Parts to check
Drum will not turn, motor runs	Broken/slipped belt	Idler pulley, drum glides
Loud squeal or scraping	Worn drum glides/bearing	Upper/lower drum glides, rear bearing bracket
Thumping or rumble	Worn support components	Glides, idler pulley, drum bearing

Why it matters

A correctly routed, properly tensioned belt keeps the drum turning at the right speed. Replacing worn glides or an idler pulley at the same time helps prevent repeat tear-downs and reduces noise and premature belt wear.

Common issues with our Hotpoint HTDX100GM7WW gas dryer include no heat, long dry times, unusual squealing or thumping noises, and the dryer not starting. Most problems trace back to airflow restrictions, worn drum support parts, or a failed ignition or safety component.

Most common symptoms and what they usually mean

• Dryer runs but won’t heat: ignition system issue (igniter, sensor), gas supply issue, or a safety device opening.
• Takes too long to dry: restricted venting, clogged lint path, or weak airflow.
• Squealing, scraping, or thumping: worn drum glides, drum bearing, or idler pulley.
• Won’t start: power supply issue, blown fuse, or door not latching.
• Burning smell or very hot cabinet: lint buildup or blocked exhaust (stop using until cleaned).

Parts that commonly fix noise and airflow complaints

If your HTDX100GM7WW is noisy or the drum feels rough, these model-matched parts are common wear items:

• Dryer drum glide bearing, upper WE03X37320
• Dryer drum glide bearing WE03X37319
• Dryer idler pulley WE03X31620
• Laundry center dryer blower wheel WE16X20393
• Dryer top drum bearing WE03X25079

Quick checks before replacing parts

1. Clean the lint screen fully; wash it with warm water if fabric softener residue is present.
2. Inspect and clear the exhaust duct; confirm strong airflow outside.
3. Listen for the type of noise:
   • High-pitched squeal often points to an idler pulley.
   • Scraping can point to drum glides or a bearing surface.
4. For “no heat,” confirm the gas shutoff valve is open and the dryer is on a heat cycle.

Symptom-to-part cheat sheet

Symptom	Most likely area	Example model-matched part
Squealing while running	Belt tension support	Dryer idler pulley WE03X31620
Scraping at front/top of drum	Drum support glides/bearing	Dryer drum glide bearing WE03X37319
Long dry times with weak airflow	Lint path or blower	Laundry center dryer blower wheel WE16X20393
Runs but no heat	Ignition system	Dryer burner igniter WE4M449

Why it matters

Airflow and drum support issues do more than cause inconvenience; they increase drying time, raise operating cost, and can lead to overheating or additional wear on the drive motor and drum components.

The main parts of a Hotpoint gas dryer like model HTDX100GM7WW include the drum (tumbles clothes), drive system (motor and belt), airflow system (blower and venting), heating system (gas burner components), and safety controls (fuses and sensors) that regulate temperature and operation.

Main dryer systems and what they do

• Drum and support parts: hold and tumble the load while reducing friction and noise
• Drive system: turns the drum using a motor, belt, and idler pulley for belt tension
• Airflow system: pulls air through the drum and pushes moist air out the exhaust
• Heating system (gas): ignites gas and transfers heat into the airflow
• Controls and safety: start/stop functions and overheat protection

Common parts you may replace on HTDX100GM7WW

These are some of the most frequently serviced components for this model:

• Drum support glides: dryer drum glide bearing, upper WE03X37320, dryer drum glide bearing WE03X37319
• Belt tension parts: dryer idler pulley WE03X31620, dryer idler pulley arm WE03X20434
• Air movement: laundry center dryer blower wheel WE16X20393
• Lint handling: dryer lint screen WE18X25100
• Heat and safety: dryer burner igniter WE4M449, dryer radiant sensor WE4X448, dryer fuse, 30-amp WE1X21975

Quick “what does what” table

Dryer part or system	What you’ll notice when it fails	Example part on this model
Drum support (glides/bearings)	Squealing, scraping, thumping	WE03X37320, WE03X37319
Drive (motor, idler)	Drum will not turn, burning smell	WE17X22217, WE03X31620
Airflow (blower, lint screen)	Long dry times, overheating	WE16X20393, WE18X25100
Gas heat (igniter, sensor)	No heat or intermittent heat	WE4M449, WE4X448
Safety (fuse)	Dryer will not run or stops mid-cycle	WE1X21975

Why it matters

Knowing which system is involved helps you troubleshoot faster. For example, long dry times usually point to airflow (lint screen, blower, venting), while no heat on a gas dryer often points to ignition or flame sensing components.
