A multimeter test can quickly confirm whether a Maytag dryer s heating element is electrically open (failed) or still continuous. It does не prove the dryer will heat under real operating conditions airflow restrictions, safety cutoffs, and burned terminals can still cause no heat.
Reference context: TUTCO describes a нагревательный элемент as a designed component (conductive + insulating materials + terminals) and notes reliability depends on environment and design choices. https://tutco.com/conductive/heating-elements

| Симптом | Quick check (no tools) | Why it matters |
|---|---|---|
| No heat, drum still turns | Check exterior vent airflow while running | Restricted airflow can overheat the system and open safeties even if the element is fine |
| Короткий нагрев, затем отключение | Inspect crushed/kinked vent hose behind dryer | Overtemp cycling often points to vent restriction |
| Burning smell / hot cabinet | Stop dryer; inspect lint screen and housing | Lint accumulation is both an airflow problem and a safety risk |
Table 1 Many heater problems start with airflow; test the element, but don t ignore the system.
- Unplug the dryer (or switch off the breaker for hardwired units).
- Verify the dryer cannot start (try turning it on nothing should happen).
- Wear gloves sheet metal edges are sharp.
- If the dryer was just running, allow components to cool.
General heater safety lesson: Whirlpool warns not to re-energize a water-heater элемент until the tank is full, or the element can burn out ( dry fire ). While the appliance differs, the principle is the same: don t energize heaters until their environment can remove heat safely. Ссылка на Whirlpool.
Maytag dryer designs vary. Some models access the нагревательный элемент from the rear panel; others require a front panel or lower kick panel removal. If available, use the model number to confirm the correct disassembly route and part layout.
- Pull the dryer forward and disconnect the vent hose.
- Remove the relevant service panel(s) to locate the heater housing.
- Identify the element terminals (usually two main terminals supplying power to the coil).
- Take a photo of wiring before removal.
- Continuity mode (beep): quick open/closed check
- Resistance ( ): confirms you re not seeing a false continuity through another path
Tip: Touch the probes together. In continuity mode you should hear a beep; in mode you should read near 0 .
- Don t test with the dryer plugged in.
- Don t leave wires connected for a resistance reading you may measure through the circuit, not the element.
- Don t pierce insulation unless you intend to properly re-terminate.
Remove at least one wire from the heating element terminal(s) so you re not measuring back through the dryer s wiring.
Place one probe on each main element terminal. A beep (or very low resistance) indicates continuity. No beep / OL usually indicates an open element.
Switch the meter to resistance ( ) and measure across the element terminals again. A healthy element typically shows a finite resistance reading (not OL ).
Resistance depends on the element s design (alloy, gauge, length) and the heater s intended power. TUTCO emphasizes that нагревательные элементы are products of design and that material properties vary by alloy and conditions. Источник.
With the element still isolated, place one probe on a heater terminal and the other on a clean, bare metal part of the heater housing/cabinet. Repeat for the other terminal.
- What you want: no continuity / very high resistance (no easy path to metal).
- What s bad: measurable continuity to chassis can indicate a shorted element or damaged insulation.
| Meter result | What it typically means | What to do |
|---|---|---|
| Terminal-to-terminal shows OL / no beep | Open element coil (failed) | Replace the heating element; inspect airflow restrictions to prevent repeat failure |
| Terminal-to-terminal shows finite | Элемент имеет электрическую цепь | Test thermal fuse/cutoffs/thermostat and inspect terminals/airflow |
| Terminal-to-chassis shows continuity | Possible short to housing | Do not operate; inspect element position and insulation; replace if needed |
Table 2 A good element can still produce no heat if safeties are open or airflow is restricted.
- Тепловой предохранитель / тепловое отключение: often opens from overheating (frequently vent-related).
- Cycling thermostat: can cause odd heating cycles.
- Heater terminals and wiring: look for discoloration, looseness, melted insulation.
- Airflow: verify strong exhaust at the outside vent while running.
Reliability note: TUTCO discusses that heater life and performance depend on environment; airflow (convection) is a major factor for heaters transferring heat to air. Ссылка.
- Clean lint screen every load
- Vacuum lint screen housing periodically
- Use a short, smooth vent path where possible
- Clean the full duct run to the outside termination
- Replace loose spade terminals
- Ensure connectors are fully seated
- Keep wiring away from hot surfaces
- Reinstall all covers/insulation
Whirlpool stresses tight wire connections during heater service (water heater context), which is directly relevant to dryer heater circuits. Источник.
Often yes, as long as you can access the terminals and disconnect at least one wire to isolate it. If you test with wires connected, you may measure through the dryer s circuit and get misleading readings.
OL typically indicates an open circuit (no continuity). Across the element terminals, that usually means the heating coil is broken.
Common reasons include an open thermal fuse/cut-off, bad thermostat, burned wiring, or airflow restriction causing safeties to open during operation.
Some resistance elements can reach red-hot temperatures in the right conditions. If glow is uneven or accompanied by burning smell or frequent shutoffs, stop and check airflow and element seating.
Fix airflow problems (venting and lint), replace loose terminals, and ensure the element is mounted correctly. Heater performance and life are strongly tied to operating environment and integration, as emphasized in TUTCO s heater engineering overview. Ссылка.
