Understanding the Problem
This guide covers the most common problems owners see on MDG6000BWW-style dryers (both electric and gas configurations): dryer won't start, won't heat, tumbles but doesn't dry, loud noises, or very long dry times. Below are the likely causes, what parts to check first, and step-by-step diagnostic and repair instructions you can follow at home. Always verify the exact OEM part number for your model before ordering. 1) Start: Identify model and power type - Verify the appliance model tag (usually inside the door opening or on the back) and confirm whether it is an electric or gas dryer. Repairs and parts differ between gas and electric units. 2) Symptom: Dryer won't heat (most common) - Likely causes to check first: clogged vent, failed thermal fuse, failed heating element (electric), failed igniter or gas valve coils (gas), failed thermostats/high-limit thermostat. - Diagnostic steps: a. Check venting: Disconnect the vent and run a short cycle. If heat returns, clean/replace venting and lint trap. Use a dryer vent brush and vacuum. b. Test thermal fuse: Unplug dryer (or turn off breaker/gas) and access the thermal fuse (usually mounted on the blower housing). Remove and test with a multimeter for continuity. No continuity = replace the thermal fuse. c. Electric dryer: Remove heating element assembly and test element and thermostats for continuity. Replace any open component. d. Gas dryer: Observe the cycle—do you hear the igniter glow and then click? If nothing, test for 120VAC to the gas valve when the dryer calls for heat. If igniter is open or gas valve coils aren’t pulling, replace igniter and/or coil kit. If you smell gas or see short cycles, stop and call a pro. - Practical repair steps (electric): Replace the thermal fuse and any failed thermostat first; replace heating element if open or visibly broken. Reassemble and test. - Practical repair steps (gas): Replace the thermal fuse if open. If igniter doesn’t glow, replace igniter; if igniter glows but gas doesn’t ignite, replace gas valve coil kit. Inspect burner tube and orifice for lint/debris and clean. 3) Symptom: Dryer won’t start or won’t tumble - Likely causes first: broken drive belt, failed door switch, failed start switch, failed motor, or control board issue. - Diagnostic steps: a. Check door switch: With dryer unplugged, press door switch and test for continuity. If no continuity when actuated, replace the door switch. b. Inspect belt and drum: Remove front panel or belt access and spin drum by hand. If belt is broken or slipped, replace belt and check drum rollers/shafts. c. Motor: If you hear humming but no spin, check motor start components (centrifugal switch/capacitor) and motor continuity. Replace motor if seized. 4) Symptom: Loud noises, rumbling or squealing - Likely causes: worn drum rollers/glide bearings, worn idler pulley, damaged blower wheel, foreign object in blower or drum seam. - Diagnostic steps and repair: Run dryer with front panel off and listen (careful of moving parts). Inspect drum rollers, idler pulley and blower wheel. Replace worn rollers or idler and clean/remove debris from blower housing. Grease bearings if serviceable. 5) Symptom: Very long dry times / clothes still damp - Likely causes: restricted venting, clogged lint screen, failing heating element (low output), faulty moisture sensor, or blocked exhaust. - Diagnostic steps: Check and clean lint screen, internal lint buildup and external vent. With vent disconnected, time a load — if dry time improves substantially, address venting. Test heating output per above steps. 6) Basic replacement steps common to most repairs - Always disconnect power (unplug or shut off breaker; for gas dryers also shut off gas supply) before servicing. - Remove top or front panel per your model's service access screws to reach the part. - Use a multimeter to confirm failed components (thermal fuse, thermostats, continuity on belts, motor windings) before replacing. - Label and photograph harness connections before disconnecting to ensure correct reassembly. - Replace failed part, reassemble panels, restore power/gas, and run a test cycle. Safety note: Gas dryers involve a gas line and ignition system. If you smell gas, stop, ventilate the area, do not operate electrical switches, and contact a qualified technician or gas company. If you are not comfortable working with gas lines, ignition systems, or mains electricity, hire a qualified appliance technician.

Helpful Repair Tip
Before ordering parts, remove the service tag on the dryer and confirm the exact model number and serial number; then cross-check part numbers with an OEM parts site. Use a multimeter to check continuity on thermal fuses and thermostats — open = replace.
Frequently Asked Questions
How can I tell if my MDG6000BWW is a gas or electric dryer?
Check the model/service tag inside the door area or on the back of the dryer. If the dryer has a gas shutoff valve and flexible gas line on the back, it's a gas dryer. If it is connected to a 240V two- or three-prong outlet, it's electric. If unsure, unplug the unit and carefully inspect the rear hookups or consult the owner manual.
Can I replace parts like the thermal fuse or igniter myself?
Yes, many homeowners can replace thermal fuses, thermostats, drum belts, rollers and igniters with basic tools. Always disconnect power (and turn off gas for gas dryers) before starting. Use a multimeter to confirm a failed part before replacing. If you are uncomfortable working with gas lines, ignition systems, or mains electricity, hire a qualified appliance technician.
