Quick answer
A propane company failing a pressure test on a Maytag LDG 412 gas dryer is a stop-use finding, not proof that a gas-valve coil is the cause. Leave the area immediately if gas is smelled or heard, do not operate switches, flames, phones or the dryer from inside, and call the propane supplier or emergency services from a safe location. Keep the dryer gas shut off and have a qualified gas-appliance professional identify the leak. Maytag installation instructions say the dryer must be disconnected from the gas piping during pressure tests above 1/2 psig; the test scope and any isolation of the appliance must therefore be confirmed by the propane company or technician, not recreated by the owner.
Before you begin
Safety first
- Do not relight, run, move, open, pressure-test, smell-test or leak-test the dryer yourself. Do not use a match, electrical switch, phone inside a suspected leak area, gauge, spray or temporary seal. Do not replace a coil, gas valve, connector or fitting based on the pressure result alone.
Work through in order
Diagnostic checks
Use only checks that match the exact appliance or system and its official guide.
-
Check 1
If gas is smelled, heard escaping, or a gas detector alarms, leave the home or area immediately. Do not light a match, turn lights or switches on or off, use a phone inside, start the dryer, or move the appliance. Call the propane supplier or emergency services from outside or from a neighbor’s phone.
Expected result: There is an odor, hissing, alarm, visible fire, or anyone has symptoms such as dizziness or headache.
Next step: Stay out until the propane supplier, fire department or emergency responder says it is safe to return. Keep the LDG 412 out of service.
Why this matters
Why: This is a potential fuel-gas or combustion emergency. A pressure-test result and lack of odor cannot make it safe for a user to investigate indoors.
-
Check 2
From a safe location and only after the propane company has made the area safe, record the Maytag model/serial, fuel type, test date, pressure-test result, where the company isolated the leak, and whether the dryer was disconnected from the gas piping. Do not pull the dryer out, open the toe panel, brush fittings, smell-test connections or use a gauge.
Expected result: The propane company can identify whether the failed section was the house supply, shutoff/connector, dryer inlet or an internal appliance section, or cannot localize it.
Next step: Give the test record to a licensed gas fitter, propane company technician or authorized appliance service and follow their written isolation/retest instructions.
Why this matters
Why: The test scope changes the next professional step. Maytag says the dryer must be disconnected from the gas piping for tests above 1/2 psig, so a result without a documented isolation boundary is not an internal-coil diagnosis.
-
Check 3
Keep the dryer gas shutoff closed and do not reconnect or run the dryer while the leak finding is unresolved. Have a qualified professional inspect the approved connector, accessible shutoff and dryer gas connection, then decide whether the appliance may be tested after repair.
Expected result: The leak remains unresolved, the connector or fitting is damaged, the appliance was moved, or the professional says the dryer section failed.
Next step: Arrange qualified gas-appliance service and replace or repair only the components the professional identifies for the exact model and fuel. Do not order a coil or gas valve from the pressure result alone.
Why this matters
Why: Maytag warns that gas connections, LP conversion and pressure checks require qualified personnel; an old connector or movement can create a hazard, and the symptom does not distinguish a valve coil from a connection or pipe.
-
Check 4
Use the complete rating-label model and serial to retrieve the Maytag manual or service path before any professional visit. Verify whether “LDG 412” is the full model as printed on the appliance and whether it is configured for the home’s fuel; do not assume a modern Maytag dryer procedure or part applies to this vintage unit.
Expected result: The rating label, fuel conversion history, connector type or exact service literature is missing or differs from the assigned text.
Next step: Pause appliance diagnosis and have Maytag support, the propane supplier or a qualified gas technician identify the appliance and approved service documentation.
Why this matters
Why: Maytag’s support path depends on the complete model and serial, and its manual warns that natural-gas/LP configuration and conversion require the correct burner and qualified technician.

Find the observation that best matches what you see, then follow the next safe action.
-
PATH 01Next step
What you see
Gas odor, hissing, an alarm, visible fire, or symptoms are present now, even if the dryer is off.
Do this next
Leave immediately, avoid switches/flames/phones inside, call the propane supplier or 911 from outside, and do not return until responders authorize it.
Why this path and its safety boundary
Why it matters: Treat the Maytag dryer and surrounding propane system as an active gas hazard; the absence of a visible leak does not make indoor investigation safe.
-
PATH 02Next step
What you see
The propane company has isolated the dryer or a section of the supply and documented a pressure failure, but no one has identified a component.
Do this next
Keep the gas shut off and have a qualified gas-appliance professional locate and repair the leak before any supervised retest.
Why this path and its safety boundary
Why it matters: The result confirms an unresolved gas-system leak boundary, not a failed coil. Maytag requires disconnection of the dryer from the gas piping for higher-pressure tests.
-
PATH 03Next step
What you see
There is no current room odor, but the propane company says the system or dryer failed a pressure test.
Do this next
Do not run the dryer or attempt a leak check; obtain the propane company’s written isolation finding and schedule qualified service.
Why this path and its safety boundary
Why it matters: No odor is not clearance. CPSC warns about gas-leak response, and Maytag’s installation material requires qualified pressure testing and proper gas connections.
-
PATH 04Next step
What you see
The full model/serial, natural-gas versus LP configuration, conversion history or failed test section cannot be confirmed.
Do this next
Stop at identity and professional-service routing; have Maytag support or a qualified gas technician establish the correct documentation and fuel configuration.
Why this path and its safety boundary
Why it matters: A modern generic Maytag procedure or a replacement coil cannot safely be mapped to the vintage LDG 412 identity.
Helpful context
Understand the symptom
A failed pressure test is not a coil diagnosis
A pressure test can show that a gas system is not holding pressure, but the result alone does not identify a Maytag LDG 412 solenoid coil, gas valve, connector, shutoff, fitting or supply line as the leak point. The opened Maytag documents describe qualified gas installation and pressure-testing precautions, while the assigned Reddit lead was inaccessible and therefore cannot establish a reported component outcome. Treat the finding as a safety and isolation problem first.
Propane safety takes priority over troubleshooting
CPSC says to leave immediately if gas is smelled or a leak is suspected, avoid lights, matches, switches and electrical equipment, and call the gas supplier or 911 from a safe location. The absence of a room odor does not authorize running the dryer: the pressure-test result still requires the propane company or a qualified gas technician to decide when the appliance and system are safe.
Confirm what the professionals tested
Maytag’s gas-dryer installation instructions distinguish the appliance from the supply piping during higher-pressure testing and require qualified personnel for LP pressure checks. Ask the propane company or technician, from a safe setting, whether the dryer was isolated, which section failed, and what must be repaired or retested. Do not move the old dryer, open the cabinet or disconnect gas fittings yourself.
When checks do not resolve it
Need a professional?
Call the propane supplier or emergency services immediately for odor, hissing, an alarm, fire or symptoms. For a failed pressure test without an active emergency, keep the gas shut off and arrange a licensed gas fitter, authorized propane technician or qualified Maytag appliance service before using the dryer.
Safety scope: Do not relight, run, move, open, pressure-test, smell-test or leak-test the dryer yourself. Do not use a match, electrical switch, phone inside a suspected leak area, gauge, spray or temporary seal. Do not replace a coil, gas valve, connector or fitting based on the pressure result alone.
Have this ready
- Provide the full rating-label model and serial, fuel type and conversion history, test date and pressure, which section was isolated, whether the dryer was disconnected during testing, connector/shutoff observations made by the professional, and any odor/alarm history.
Common questions
FAQ
Can a faulty gas-valve coil cause the Maytag LDG 412 pressure test to fail?
The pressure result alone cannot identify a coil. It may indicate a leak somewhere in the appliance or supply system, and the opened official material does not assign this symptom to a coil. Keep the gas off and have a qualified professional isolate and diagnose the leak.
Is it safe to run the dryer if there is no smell of propane?
No. A failed pressure test remains unresolved even without a room odor. Do not run the dryer or attempt to confirm the leak yourself; follow the propane company’s isolation instructions and obtain qualified service.
Why does the pressure-test scope matter?
Maytag says the dryer must be disconnected from the gas piping during pressure tests above 1/2 psig. That means a professional must document whether the test covered the house piping, connector, shutoff or appliance before anyone can interpret the result; it does not justify owner testing.
