Understanding the Problem
This guide covers the most common problems owners see on the Whirlpool/Maytag FGHD2433KW1 gas dryer and gives clear, step-by-step diagnostics and repairs. Start by identifying the symptom (won't start, no heat, long dry times, loud noise), then follow the numbered checks below to isolate the failed part and perform the repair. 1) Dryer won't start (no drum rotation) - Check: Is the dryer getting power? Confirm outlet has 120VAC using a multimeter. Inspect the plug and cord for damage. - Check door switch: Press the door switch and listen for a click; test continuity with multimeter (closed when door is shut). Replace switch if no continuity. - Check start switch and control: With power off, check the start switch for continuity when pressed. If the motor hums or doesn't start, test motor windings for continuity and resistance. Replace motor assembly if motor windings are open or burnt smell present. - Check thermal fuse: A blown thermal fuse can prevent start in some designs. Locate the thermal fuse on the blower housing and test for continuity; replace if open. - Repair tips: Replace failed parts (door switch, start switch, motor, thermal fuse). If replacing motor, inspect belt, idler pulley, and drum rollers while cabinet is open. 2) Dryer runs but no heat (gas dryer) - Confirm gas supply: Ensure gas valve to the dryer is ON and other gas appliances work. If you smell gas, stop and call a pro. - Check igniter: On gas models, the igniter glows to open the gas valve. Access igniter assembly (behind front panel or service panel) and check for visible cracks and continuity with a multimeter. Replace if open or visibly damaged. - Check gas valve coils/solenoids: If igniter glows but no gas flame, the gas valve solenoids may be bad. Test coil resistance against manufacturer specs (typically low ohms). Replace the gas valve solenoid kit if coils are open or out of spec. - Check flame sensor (gas flame detector) and thermostat/high-limit: A failed flame sensor or high-limit thermostat can keep the burner off. Test for continuity and replace if defective. - Check venting and air flow: Restricted venting or clogged lint screen can cause overheating and safety components to cut heat. Clean vent and exhaust path; test dryer with vent disconnected to isolate heating problem. - Repair tips: Replace igniter or gas valve solenoid kit as required, clean vents, and replace failed thermostats or flame sensors. 3) Long drying times or clothes come out damp - Check lint filter and venting: Clean lint screen, vacuum lint trap, disconnect and check exhaust duct and outside vent damper for blockages. Measure airflow at dryer exhaust — should be strong. - Check drum seals and rollers: Worn seals or rollers can allow air leaks and reduce drying efficiency. Inspect drum seals, rollers, and idler pulley; replace worn parts. - Check moisture sensor: If dryer has a moisture sensor and it’s coated with residue it may misread. Clean sensors with rubbing alcohol. If faulty, replace sensor or control board sensor harness. - Repair tips: Clean vent thoroughly (including outside) and replace worn drum rollers/doors seals. Consider professional vent cleaning if long runs or metal ducting has accumulated lint. 4) Loud noise, rumbling, scraping - Inspect drum support components: Remove front or rear access and spin drum by hand. Listen for rough bearings, squeals, or metal-on-metal grinding. - Check drum rollers and bearings: Worn rollers or bearings are a common cause. Replace drum rollers, shafts, and rear drum bearing glide as needed. - Check idler pulley and belt: A worn idler pulley will squeal or rumble; a frayed belt will slap or snap. Replace pulley and belt if worn. - Check blower wheel: Remove blower housing and inspect for broken blades or foreign objects. Replace blower wheel if damaged. - Repair tips: Replace parts showing wear (rollers, idler, blower wheel) and lubricate bearings only where manufacturer allows. 5) Intermittent operation or control problems - Check door switch and start circuit: Intermittent clicks or failure to start point to a failing door switch or start button. - Check user interface / control board: If settings don't change or cycles stop, the control board or control console may be faulty. Inspect for burnt components or connectors and test inputs/outputs if you have a service manual. - Repair tips: Replace the user control or main electronic control if confirmed defective. Safety note: Always disconnect power (unplug) before accessing internal components. For gas-related diagnostics (igniter, gas valve coils, gas supply) shut off gas supply before disassembly and relight pilot or test flames only if you are comfortable and safe doing so. If you smell gas or are unsure, stop and call a licensed technician. Use a multimeter set to the right range and follow manufacturer safety procedures.
Common Symptoms
Dryer won't start, drum spins but no heat, long drying cycles, loud rumbling or squealing noise, intermittent control issues.
Common Causes
- Failed igniter or gas valve solenoids (no heat)
- Blown thermal fuse or faulty door/start switch (no start)
- Clogged venting or lint build-up (long dry times)
- Worn drum rollers, idler pulley, or blower wheel (noise)
- Faulty moisture sensor or control board (poor cycles)

Helpful Repair Tip
If your dryer tumbles but doesn't heat, watch the igniter during a heat cycle: if it doesn't glow, replace the igniter; if it glows but no flame appears, the gas valve solenoids are most likely faulty.
Frequently Asked Questions
How do I test the igniter on my FGHD2433KW1 dryer?
Run a heat cycle and watch the igniter through the burner access or test with a multimeter for continuity. If the igniter doesn't glow or has no continuity when cool, replace the igniter assembly. Always cut power and gas before replacing gas components.
My dryer runs but takes forever to dry — can I fix it myself?
Often yes: first clean the lint trap, then disconnect the exhaust vent and run the dryer briefly to see if drying improves (if it does, clean the vent). Also check the dryer vent hood outside for blockage. If airflow is good but drying is still slow, inspect drum seals, rollers, and the moisture sensor; those parts are user-replaceable with basic tools.
