Answers from 17+ years of appliance repair experience in Port St. Lucie
Why is my dryer not heating?+
A blown thermal fuse is the #1 cause of a dryer not heating. The thermal fuse is a one-time safety device that blows when the dryer overheats — once blown, the dryer runs but produces zero heat. Cost to replace: $80–$130. Electric dryers: also check the heating element ($120–$220). Gas dryers: check the igniter and gas valve solenoids ($80–$180). In every case, check the dryer vent for lint blockage — a clogged vent causes the thermal fuse to blow in the first place. Treasure Coast Appliance Repair carries all these parts for same-day repair in Port St. Lucie. Call (772) 353-5791.
Why is my dryer taking too long to dry clothes?+
A clogged dryer vent is the cause 90% of the time. Lint buildup restricts airflow, trapping moisture inside the drum so clothes can't dry in one cycle. Check the outside vent flap — it should blow open strongly when the dryer runs. If airflow is weak, the vent needs professional cleaning ($80–$150). Other causes: a dirty lint screen (clean before every load), a failing heating element producing weak heat ($120–$220), or a worn felt seal letting cold air in ($80–$150). Treasure Coast Appliance Repair handles vent cleaning and dryer repair in the same visit in Port St. Lucie. Call (772) 353-5791.
Why is my dryer making a loud squeaking noise?+
Squeaking or squealing sounds from a dryer are caused by worn drum rollers (most common), a dry or failing idler pulley bearing, a slipping drive belt, or worn drum glides. The drum rollers support the drum as it spins — when the bearings wear out, metal-on-metal contact creates a high-pitched squeak. This repair costs $100–$220 at Treasure Coast Appliance Repair.
Why is my dryer not tumbling?+
A dryer that heats but won't tumble has a broken drive belt (the most common cause), a failed drive motor, or a seized drum roller. The belt wraps around the drum, motor pulley, and idler pulley — when it snaps, the drum simply stops turning. Belt replacement is one of the most affordable dryer repairs at $100–$180.
Why is my dryer not starting at all?+
Check the power supply first — electric dryers need both legs of the 240V circuit (dryers need 240V — both breakers must be on), test the door switch by pressing it manually, check for a child lock setting, and try unplugging for 60 seconds. If power is confirmed and the door switch clicks, the start switch, thermal fuse, or control board has failed. Call Treasure Coast Appliance Repair at (772) 353-5791.
Why is my dryer overheating?+
An overheating dryer is a fire hazard. The most common cause is a clogged vent restricting airflow — hot air can't escape and builds up inside the drum. Other causes include a failed cycling thermostat (doesn't cycle the heater off), a stuck gas valve, or a shorted heating element. Stop using the dryer immediately and call Treasure Coast Appliance Repair. We prioritize overheating calls.
Why does my dryer smell like it's burning?+
A burning smell from your dryer is urgent. Causes include lint buildup in the vent duct (fire hazard), a worn or slipping drive belt, a failing motor overheating, a stuck dryer sheet on the heating element, or excess lint inside the cabinet around the heater. Stop the dryer, unplug it, and do not use it until inspected. This is the #1 dryer fire warning sign.
Why is my dryer making a thumping or banging noise?+
Thumping sounds are caused by worn drum support rollers — the rubber coating wears flat and creates a rhythmic thump with each rotation. Other causes include loose drum glides, a heavy item (shoes, zipper) banging inside, or a damaged blower wheel hitting the housing. Drum roller replacement costs $100–$200 at Treasure Coast Appliance Repair.
Why are my clothes coming out wrinkled from the dryer?+
Overloading the drum is the #1 cause — clothes can't tumble freely when packed too tight. Other causes include drying on too-high heat, leaving clothes sitting in the drum after the cycle ends, or mixing heavy items (jeans) with lightweight items (shirts). Use the wrinkle guard/extended tumble feature and remove clothes promptly. This is a usage issue, not a mechanical problem.

Why is my dryer not drying on one cycle?+
The dryer vent is clogged. Check the outside vent flap — it should open fully when the dryer runs. If airflow is weak, the vent needs cleaning. A vent that's too long (over 25 feet), has too many turns, or uses flexible ribbed ducting dramatically reduces drying performance. Treasure Coast Appliance Repair cleans vents and repairs dryers in the same visit.
Why does my dryer keep shutting off after a few minutes?+
A clogged dryer vent is overheating the drum, triggering the thermal fuse or high-limit thermostat to cut power as a fire safety measure. Other causes: a failing drive motor that overheats under load, a defective door switch that intermittently loses contact, or a faulty moisture sensor ending the cycle prematurely. Vent cleaning ($80–$150) fixes this 80% of the time.
Why is my dryer drum not turning but the motor runs?+
The drive belt has broken — you can hear the motor running but the drum won't spin. The belt wraps around the drum and connects to the motor via the idler pulley. When it snaps, the motor spins freely but can't turn the drum. Belt replacement is straightforward and costs $100–$180 at Treasure Coast Appliance Repair.
Why is my gas dryer not lighting?+
Gas dryers use an igniter to light the gas. If the igniter glows but doesn't ignite gas, the gas valve solenoid coils have failed — this is extremely common in gas dryers over 5 years old. If the igniter doesn't glow at all, the igniter itself is cracked. Igniter replacement costs $100–$180. Gas valve coils cost $80–$150. Our technicians carry both parts.
Why does my dryer leave lint on clothes?+
Excessive lint on clothes after drying is caused by a full lint screen (clean before EVERY load), a damaged lint screen, a torn or missing lint duct seal, or a clogged exhaust vent pushing lint back into the drum. Also check for deteriorating drum seals — worn felt seals allow lint to bypass the filter. Our Port St. Lucie technicians fix lint issues daily.
Why is my dryer making a humming noise but not starting?+
A humming dryer that won't start usually has a seized drum — the motor tries to turn but can't overcome resistance. Common causes: a seized roller bearing, a broken belt wrapped around the motor shaft, or a foreign object jamming the blower wheel. The motor's thermal overload will eventually trip and shut it off. Call Treasure Coast Appliance Repair.
Why does my dryer stop before clothes are dry?+
Premature cycle ending is caused by a faulty moisture sensor — the sensor thinks clothes are dry when they're not. Clean the moisture sensor bars (metal strips inside the drum near the lint filter) with rubbing alcohol, as fabric softener residue coats them. If cleaning doesn't help, the sensor or control board needs replacement — $100–$200.
Why is my dryer tripping the circuit breaker?+
A dryer tripping the breaker repeatedly indicates a short circuit in the heating element, a grounded motor, damaged wiring, or a failing terminal block. Electric dryers use 240V and draw significant current — electrical faults are serious. Stop using the dryer and call Treasure Coast Appliance Repair immediately. Do not repeatedly reset the breaker.
Why is my dryer producing static in clothes?+
Static buildup happens when clothes are over-dried, especially synthetic fabrics. Reduce heat settings, use the moisture sensor cycle instead of timed dry, and remove clothes while slightly damp. Florida's low-humidity winter months (yes, they exist) make static worse. Dryer sheets or wool dryer balls reduce static. This is a usage issue, not a mechanical problem.
Why does my dryer have condensation on the inside of the door?+
Condensation on the dryer door means exhaust moisture isn't venting properly. The vent duct is likely clogged, kinked, or disconnected behind the dryer. Check the outside vent flap — if little to no air comes out when the dryer runs, the vent is blocked. In Florida's humidity, condensation issues are amplified. Get the vent cleaned professionally.
Why is my dryer not spinning smoothly?+
A dryer that wobbles, vibrates, or spins unevenly has worn drum rollers, a damaged drum bearing (rear), or worn drum glides (front support pads). The drum should spin freely by hand. If it feels rough or wobbles, the support components need replacement. Continuing to run with worn rollers damages the drum shaft — fix it promptly.
Why does my dryer get hot but clothes stay damp?+
Hot air reaching the clothes but not drying them means the moisture has nowhere to go — the vent is clogged and humid air recirculates inside the drum. Even though the heating element works fine, trapped humidity prevents evaporation. A clogged vent is the cause 90% of the time. Treasure Coast Appliance Repair cleans vents for $80–$150.
Why is my dryer timer not advancing?+
The timer motor has failed — the dryer runs but the dial stays in one spot and won't advance. On cycles using the moisture sensor (auto-dry), the timer won't advance until the sensor detects dry clothes — if the sensor is faulty, the timer appears stuck. True timer motor failure costs $120–$200 to repair.
Why does my dryer shake violently during operation?+
Violent shaking is caused by an unbalanced load, the dryer not being level, worn drum support rollers that allow the drum to bounce, or a damaged blower wheel that's off-balance. Level the dryer first. If it still shakes with a properly distributed load, the rollers or blower wheel need replacement.
Why is my electric dryer only partially heating?+
Electric dryers have two heating coils. If one coil breaks, the dryer produces half its normal heat — enough to warm the drum but not enough to dry effectively. The element looks visually different — one coil will have a visible break. Full element replacement costs $100–$200 at Treasure Coast Appliance Repair.
Why does my dryer keep blowing thermal fuses?+
Repeated thermal fuse failures point to a restricted vent (the #1 cause), a failed cycling thermostat, or a clogged lint trap area. The thermal fuse is a safety device that blows when temperatures exceed safe limits. Replacing the fuse without fixing the root cause will result in another failure. We always check the vent and thermostat when replacing thermal fuses.
