A dryer that won't heat, takes multiple cycles to dry a single load, or shuts off before the cycle ends is a performance problem and — in the case of a blocked exhaust vent driving extended cycle times — a fire safety concern. A dryer fire in a Potomac home almost always starts in the exhaust vent, not the appliance cabinet, and almost always involves lint accumulation in a restricted vent.
UP Appliance Repair serves Potomac, MD with same-day dryer repair that addresses both the appliance fault and the exhaust system — because a repair that fixes the heating element without checking the vent isn't a complete dryer repair.

On electric dryers, the heating element is the most commonly failed component in Potomac, MD — confirmed through resistance testing, not visual inspection. A blown thermal fuse is the second cause — the fuse blows when the dryer exceeds a safe temperature threshold and cannot be reset. The underlying cause of the overtemperature event that blew the fuse must be identified alongside the fuse replacement, or the replacement fuse will blow again for the same reason in Potomac.
On gas dryers, a weak or failed igniter is the most common no-heat cause in Potomac, MD. Igniter current draw testing is the correct diagnostic method — an igniter that draws insufficient current to reach the temperature required to open the gas safety valve appears to function visually but fails to produce the thermal output needed for ignition. A failed gas valve solenoid coil is the second cause — the coils open the valve to allow gas flow when the igniter reaches temperature, and when they fail, no gas reaches the burner regardless of igniter function.
The drive belt is the first component we assess — a broken belt produces a drum that won't rotate despite motor operation and is confirmed by direct inspection after panel removal. The idler pulley is the second — a seized idler pulley bearing loses belt tension and allows the belt to slip rather than drive the drum. The drive motor is the third — a motor that has seized or burned out fails to rotate the drum regardless of belt and pulley condition. We test the motor by assessing start winding resistance and run winding resistance before removing it — a motor with correct resistance values is more likely to have a mechanical seizure than a winding failure in Potomac, MD.
The exhaust vent is the first and most important assessment point on every extended drying time call in Potomac — because a blocked or restricted vent is the most common cause of extended drying and the most common precursor to dryer fires. We assess the full exhaust path from the lint trap housing through the transition duct and duct run to the exterior vent flapper — measuring airflow output and comparing it against normal parameters for the specific duct length and configuration in Potomac, MD.
A failing cycling thermostat not maintaining adequate heat output is the second cause. A worn drum seal allowing heated air to escape from the drum is the third. A damaged or undersized blower wheel not moving adequate air volume is the fourth in Potomac.
The high-limit thermostat is the most common protection circuit trigger in Potomac — the dryer's internal temperature has exceeded the safe threshold, almost always because of exhaust vent restriction. The cycling thermostat failing in the off position is the second cause — it produces a dryer that heats briefly and then stops heating, with the drum continuing to rotate through a cold cycle. A moisture sensor coated with fabric softener residue reads clothes as dry before they are and terminates the cycle prematurely — producing a consistent early termination at approximately the same elapsed cycle time every load in Potomac, MD.
Thumping during drum rotation — worst at the start and improving after a few minutes — indicates worn drum support rollers that become flat-spotted when the dryer sits stationary. Squealing during spin engagement indicates drive belt glazing or fraying. Grinding during all phases of drum rotation indicates worn drum glides or a damaged front drum bearing. Rattling from the dryer cabinet indicates a loose drum baffle, a broken drum fin, or a foreign object that has entered the cabinet through the lint trap in Potomac, MD.
External power supply is verified first — an electric dryer requires a 240-volt supply from a dual-pole breaker, and a single tripped breaker leg produces a dryer that tumbles without heating rather than a dryer that won't start at all. Both breaker legs must be confirmed for a complete no-start diagnosis in Potomac, MD. The door switch is tested second — it's the most common cause of a dryer that won't start. The thermal fuse is tested third. The start switch is tested fourth. The control board is assessed last — only after all the above have been confirmed functional in Potomac.
Exhaust vent restriction is the primary cause of dryer overheating in Potomac — we inspect the full exhaust path on every overheating call, including lint trap housing, transition duct, duct run material and diameter, duct length and bend count, and exterior vent flapper operation. A cycling thermostat that has failed in the always-on position — leaving the heating element energized continuously rather than cycling it — produces overheating without any vent restriction. We test thermostat function alongside vent assessment on every overheating diagnosis in Potomac, MD.

The igniter is tested through current draw measurement — not through visual assessment of whether it glows. An igniter that draws insufficient current to trigger the gas valve appears to function visually but fails to produce the thermal output required for ignition. Testing current draw rather than appearance distinguishes a weak-but-visually-functional igniter from an intact igniter in Potomac, MD. The gas valve solenoid coils are tested through resistance measurement. The radiant flame sensor is tested through continuity at operating temperature — a failed sensor allows the burner to light briefly and then extinguishes it, producing the characteristic intermittent heat symptom of flame sensor failure in Potomac.
Every gas dryer repair completed by UP Appliance Repair in Potomac, MD includes a post-repair gas connection check — verifying all accessible gas fittings are leak-free using appropriate detection methods before the job is considered complete in Potomac.
We test supply voltage at the dryer outlet — confirming both legs of the 240-volt supply are present and correct — before testing any internal heating component in Potomac. A single tripped breaker leg on the dual-pole circuit produces a dryer that tumbles without heating, mimicking heating element failure at zero parts cost if the breaker is the actual cause. Heating element resistance is tested after supply confirmation. Cycling thermostat, high-limit thermostat, and thermal fuse function are tested in sequence — confirming the full thermal circuit integrity before the repair is recommended in Potomac, MD.
Ventless condenser dryers remove moisture by cooling the exhaust air until moisture condenses. Condenser blockage with lint and debris is the most common ventless dryer performance fault in Potomac, MD — the condenser needs regular cleaning to maintain heat exchange efficiency, and when blocked, produces extended drying times and thermal protection activation that mirrors vent blockage symptoms in standard vented dryers. Condensate pump failure prevents water removal and stops dryer operation when the reservoir reaches capacity. We service ventless condenser dryers from Bosch, LG, Samsung, Electrolux, Miele, and other brands across Potomac, MD with specific knowledge of their condensation system architectures in Potomac.
Samsung D80, D90, and D95 vent blockage codes indicate progressively severe airflow restriction — each code represents a measured percentage of normal airflow remaining and directs our vent inspection to the severity level the code indicates. HE heating errors and FE fan errors direct testing toward the heating element circuit and the drum fan respectively. We service all Samsung configurations across Potomac, MD including DV series and WashTower combined units in Potomac.
LG D80, D90, and D95 vent codes indicate the same airflow restriction severity levels as Samsung's equivalent codes and direct our vent inspection accordingly. We service all LG dryer configurations across Potomac, MD — including TurboSteam gas and electric models, sensor dry systems, and the WashTower combined unit — with specific knowledge of LG's control architecture in Potomac.

UP Appliance Repair includes exhaust vent inspection as a standard component of every dryer repair visit in Potomac — not as an optional service or an upsell. The vent inspection covers the lint trap housing, transition duct, duct run, and exterior vent flapper on every call. A dryer repair that restores heat without assessing the vent isn't a complete repair in Potomac, MD.
UP Appliance Repair replaces thermal fuses alongside identification of the root cause that blew them — not as a standalone repair that leaves the underlying cause in place. A thermal fuse replaced without addressing the vent restriction or thermostat fault that caused it to blow will blow again in Potomac, MD. That's a service call that costs twice what it should in Potomac.
