Question about Maytag Neptune MDG5500AW Gas Dryer

The dryier does not heat

My dryier is not producing heat. When I put it on the time cycle, I hear the gas ignite, but after a while it shuts off and never comes back again. When I put the dryier on sensor dry, I can't even hear the gas come on.

Viking VGIC oven burners ignite but cycle off repeatedly temperature rarely gets to 300 after 30 minutes. If igniters ignite is problem elsewhere - like bad bi-metal valve? Range and broiler work OK,


There is a sensor that detects the oven temperature, it must be defective and sending a signal that oven is at set temperature and this shuts off the gas valve.

Heater is cycling on and off, less then one minute cycle time between cycles. Sometimes SPK code comes on and stays on without firing. Have shorted water press switch with no effect. Pretty sure gas...


The SPK Code, indicates that there is power to Igniter and should be producing a Spark to ignite fuel! If this is actually the case, then it is NOT a safety sensor issue, The igniter serves a dual purpose: produce a spark, and then CONFIRM a flame is consuming the fuel. If it does not get a proper Milivolt reading, then gas valve will shut off, hence a cycle occurs. Not enough reading is the same to the heater as no reading! Safety issue. If gas valve stays open, and no flame to consume raw fuel, it will build up and accumulate then when ignition takes place, it go...BOOM! Not Good.
Either insufficient fuel supply/pressure or faulty igniter. It's also not a Gas Valve. It's a simple switching valve, either open or closed.

I have a gas dryer, model MDG7657AWW that will not stay heated. Every time I put it on, the flame comes on for about 21 seconds & then shuts off. I replaced the igniter, hi limit thermostat, cycling t


On a gas dryer the heat normally only comes on for 30 seconds or until the drum temp reaches 160f at which time the flame is shut down by the cycling thermostat. The drum temp then starts to drop. When the drum temp reaches 105f then another blast of heat is issued for 30 more seconds.That is how they work. Put it all back together and trow a load in there.

Problem: Your furnace will not ignite the gas to produce heat for your home. When a furnace has a bad ignitor what I see most of the time is the following sequence of operation:


1. Thermostat calls for heat. 2. Draft inducer motor starts. 3. Pressure switch attached by a small plastic or rubber tube senses the negative pressure produced by the draft inducer and closes. 4. Draft inducer runs for 30 seconds to a minute before you hear a gas hissing sound. The ignitor did not glow, the flame sensor (a small metal probe about 1/8" in diameter, with a white porcelain base) does not sense the flame, so after 8 to 10 seconds the hissing sounds stops with no ignition of gas to heat your home. Your furnace shuts down and goes into a lock out condition until you turn your power switch back off and on again. Then the sequence starts all over again with no ignition of the gas. Solution:You probably need to purchase and install a new ignitor. I would suggest that you inspect your ignitor closely for cracks. Make sure you do not touch the ignitor with your bare hands. If you do not visually see a crack, then you could have a furnace control board problem or a limit, rollout switch problem. The furnace's control board might not be supplying the voltage to the ignitor.If your furnace lights and the gas stays on for 8 to 10 seconds, then shuts right back off, then you need to clean your flame sensor with light sand paper or steel wool. You might need a new flame sensor, but most of the time they can be cleaned an will work well after cleaning.

Will not heat up in any cycle


If this is an ELECTRIC dryer, the following link will give you some advice on how to troubleshoot a no heat problem:

http://www.fixya.com/support/r3576548-dryer_runs_but_does_not_heat

If this is a GAS dryer, the most common failure for heat related problems in a gas dryer is a weak or blown igniter on the burner assembly. The way the ignition system is supposed to work is like this:

1. Select the dryer cycle and press start.
2. The drum begins to spin and the igniter begins to glow.
3. Once the igniter reaches a certain current potential, the gas safety valve opens.
4. Gas is introduced into the manifold and you have ignition.

  1. NOTE: It can take roughly 30 – 90 seconds from the time you start the dryer to the time it takes for the gas to ignite.

NOTE: This is a designed safety feature of the appliance that prevents free flowing gas from accumulating in your home without ignition. That’s why you typically don’t hear any gas flowing when you have an igniter problem. You might think you have a gas problem when actually you have an ignition problem.

TWO BASIC IGNITER TYPES:

Carborundum (Cylindrical in shape) – needs to produce 2.5 to 3.0 amps for the gas safety valve to work.
Norton (Rectangular in shape) – needs to produce 3.2 to 3.7 amps for the gas safety valve to work.

NOTE: There is a UNIVERSAL FLAT BAR igniter on the market as well, that can be used as a substitute if the igniter type that came with your range is not available.

The igniter typically goes bad in one of two ways, the igniter either stops glowing completely, or becomes weak over time and doesn’t produce enough current to open the gas safety valve (in this case the igniter will still glow but the dryer still won’t light). Longer ignition times can be another symptom of an igniter possibly going bad.

You can purchase a replacement at any of the following websites:

searspartsdirect.com
pcappliancerepair.com
appliancepartspros.com
repairclinic.com

The first three sites on the list also offer some excellent exploded view diagrams of the appliance.

If your replacement igniter comes with a connector plug that does not match your appliance, you will be instructed to cut the old plug off and splice the wires together using ceramic wire lugs included in the kit. Do not use standard wire lugs as they will melt.

If you have any questions, please post back with your complete model number (located on a nameplate around the door opening) and let me know. I hope this helps you.

After a few heating cycles the burner does not ignite


The problem you are describing is usually associated with a bad gas valve coil. The dryer runs normally until it gets hot, then starts making a strange clicking noise. After it cools down, the dryer runs normally again. The gas valve coils (there are two of them) usually run about $20 a piece. I recommend replacing both of them at the same time just to be sure. I hope this helps.
