How to Install Thermistor WR55X10545 in a GE Dryer
If your GE dryer is not working properly, the thermistor may be part of the problem. This small sensor helps the control system read temperature. When it fails or reads poorly, the dryer may act in odd ways. You may see weak heat, poor drying, or cycles that do not behave as expected.
How to Install Thermistor WR55X10545 is a job many careful DIY repair owners can handle. Plan for medium difficulty and a 30-60 minute repair window. The exact access steps can vary by model, so move slowly and keep each screw organized.
This guide uses only the supplied part and model details. The listed compatible models are ZDIC150WBB, ZDIC150WBBA, ZDIC150ZBBE, ZDIS150WSS, and ZDIS150WSSD. Before you order or install any part, match your full model number on the appliance tag.
Before You Start
A thermistor is a temperature-sensing part. In a dryer, temperature feedback matters. The control system needs that reading to manage heat and cycle behavior. When the reading is wrong, the dryer may not work the way you expect.
This repair is not a race. Give yourself enough light, room, and time. A rushed repair often leads to lost screws or damaged wire connectors.
Use this job plan if you have WR55X10545 and a matching GE model from the list above. If your model number does not match, stop before installing the part. A close-looking part can still be wrong.
GE also offers general support and maintenance resources for laundry products through its washer and dryer support page. Use brand support when your symptoms do not match a normal part failure.
What the Thermistor Does
The thermistor changes resistance as temperature changes. The dryer control reads that change and uses it as temperature information. This helps the machine decide how to manage heat and cycle timing.
A bad thermistor can confuse that system. The dryer may run, stop, heat poorly, or fail to respond as expected. Since the symptom list here only states “dryer not working properly,” avoid guessing too far. Treat the thermistor as one possible cause, not the only cause.
A wiring issue can look like a bad thermistor. So can a control issue, airflow restriction, or another heat-related failure. Good repair work means checking the basics before replacing parts.
Confirm Your Model and Part
Find the model tag on your appliance before opening the cabinet. Look for the full model number, not a partial match. Compare every letter and number.
The compatible models supplied for this part are:
| Supplied compatible model |
|---|
| ZDIC150WBB |
| ZDIC150WBBA |
| ZDIC150ZBBE |
| ZDIS150WSS |
| ZDIS150WSSD |
Use WR55X10545 as the part number for this repair. Do not rely on photos alone. A part can look right and still fail to fit or work.
If the model tag is damaged, take a clear photo of the full appliance label. Then contact support before ordering. Guessing wastes time and can create a second repair problem.
Safety First
Disconnect power before you remove panels or touch wiring. A dryer has electrical parts behind the cabinet. Treat every wire as live until power is off.
Pull the plug if the dryer uses a standard cord. If the unit is hardwired, turn off the correct breaker. Confirm the machine will not start before you continue.
Let the dryer cool before work begins. Hot metal and nearby parts can burn your hands. Wear work gloves if the cabinet edges feel sharp.
Move the dryer only as far as needed. Avoid pulling on the power cord, vent, or any hose. If access feels unsafe, stop and call a qualified technician.
GE provides general maintenance and troubleshooting videos on its maintenance videos page. Use those resources for safe product handling and support basics.
Tools and Supplies
The supplied article data does not include a tool list. Use a basic repair setup and adjust as needed for your dryer.
Common tools may include:
- Phillips screwdriver
- Flat blade screwdriver
- Nut driver set
- Needle nose pliers
- Work gloves
- Small container for screws
- Flashlight
- Phone camera for reference photos
Do not force a tool that does not fit. A stripped screw turns a medium repair into a hard one. If a fastener does not move, apply steady pressure and check the tool size again.
Place removed screws in order. Cabinet screws can look similar but serve different spots. A small parts tray keeps the repair clean.
Difficulty, Time, and Skill Level
This job has a medium difficulty rating. That means you need basic comfort with panels, wire connectors, and careful reassembly. It does not mean you need advanced diagnostic tools for every step.
Most careful DIY owners should plan for 30-60 minutes. Add extra time if the dryer sits in a tight laundry space. Access often takes longer than the part swap.
The hardest part is usually reaching the thermistor without damaging wiring or panels. Good photos help. Take a photo before disconnecting any wire connector.

Common Mistakes to Avoid
Do not skip the model check. A wrong part can waste the whole repair. Match the full model number before installation.
Never pull on wires to remove a connector. That can loosen terminals inside the connector. A damaged connector may cause an intermittent failure.
Do not leave lint packed around the sensing area. Lint can affect airflow and heating behavior. Clean what you can reach safely.
Avoid forcing panels into place. A panel that will not fit often means a wire or tab is in the wrong spot. Remove the panel and inspect the area again.
Do not keep running the dryer if it acts unsafe. Repeated testing can make a small problem worse. Stop and inspect before trying again.
Original Repair Decision Matrix
Use this matrix before you decide whether to replace the thermistor, inspect further, or call for help.
| What you see | What it may mean | Best next step |
|---|---|---|
| Dryer is not working properly, and model matches the supplied list | Thermistor may be a valid repair path | Install WR55X10545 with safe access |
| Connector looks loose or damaged | Wiring may be part of the fault | Repair or inspect connector before blaming the part |
| Heavy lint sits near the sensing area | Airflow may affect performance | Clean accessible lint and check vent path |
| Dryer still acts the same after replacement | Another part may be involved | Stop and diagnose before buying more parts |
| Model number does not match | Part fit is not confirmed | Do not install this part |
This table keeps the repair honest. A thermistor can solve temperature feedback problems, but it cannot fix every dryer issue. Careful checks help you avoid parts guessing.
Airflow Matters After the Repair
A dryer depends on airflow. Even a good thermistor cannot overcome a blocked vent or packed lint path. Poor airflow can cause weak drying, long cycles, or heat-related problems.
Clean the lint screen before every load. Check the vent hose behind the dryer. Make sure it is not crushed when you push the dryer back.
Look outside at the vent hood while the dryer runs. Air should move freely. If airflow seems weak, the vent path may need cleaning.
Do not treat vent care as optional. Temperature sensors work best when air can move as designed. A clean airflow path helps the dryer control heat more accurately.
When the Thermistor May Not Be the Cause
A dryer not working properly is a broad symptom. The thermistor is one possible cause, but not the only one. Other electrical, airflow, control, or heating issues may create similar behavior.
If the dryer will not power on, check the power source first. A tripped breaker or loose plug can look like a machine failure. Do not open the dryer until power is safely disconnected.
If the dryer runs but does not dry well, check airflow before replacing more parts. A clogged vent can mimic other failures. It can also create unsafe heat conditions.
If the control behaves oddly after the part change, inspect the connector again. A connector that is not fully seated can cause poor readings. Use your photo to confirm routing and placement.

Internal Repair Notes for Careful DIY Owners
Read the appliance tag in good light. Take a photo before ordering and before repair. That small step prevents many wrong-part problems.
Keep the old thermistor until the dryer passes a full test load. Do not throw away any original part right away. If the symptom remains, the old part may help with comparison.
Label screws if you remove more than one panel. Many dryers use similar fasteners in different areas. Mixing them can lead to loose panels or stripped holes.
Keep the work area clean. A dropped screw inside the cabinet can cause noise later. Use a flashlight before closing the dryer.
