Question about Goodman GMS807034ANA Heater

2 Answers

Gas heater doesn't stay on longer than 5 minutes.

When i turn my thermostat on the heat element and the vent motor turns on at the same time and it starts blowing hot air. this only lasts about 5-10 min until the heating element shuts off and it blows cold air for the rest of the time. It doesn't stop because it reached the temperature it was supposed to because my house stays cold all the time and i would like my heater to stay on. Any assistance would help? Thank you!

It sounds to me that your air flow is restricted somewhere. The first thing to check is your air filter. If that gets real dirty your restricted air flow will cause the hi-limit(hi temperature limit switch) in your heat exchanger compartment to over heat and open up your gas valve electrical circuit,thus, shutting off the gas to your burners. After the hi-limit switch cools down the furnace will go back to heating again then it will overheat again(you get the picture?) If it keeps cycling on and off like that the house will never get warm if it is cold outside. If your air filter is reasonably clean(you should be able to see light thru it easily) then the secondary heat exchanger could also be dirty, this is located above the indoor fan housing, you would need to pull the indoor blower assembly out of the furnace and look up above. The secondary heat exchanger looks similar to a radiator will fins. You can use a medium stiff plastic brush to brush the dirt,hair, whatever off of it. Another problem spot would be the cooling evaporator coil (if you have central airconditioning) located most likely above the furnace in the plenum(if your furnace is in a basement). This usually is difficult to access if an access cover wasn't installed when the airconditioning was installed. I would recommend an experience service tech to clean it for you. Also make sure all you supply air registers and return air registers are open . These are the things I would check first. Good luck!!

This sounds to be a possible deffective fan limiting switch. It over rides everything if it thinks the heater is overheating,shutting off the gas and running continuously. You can pick up a fan limiting switch at a heating and air conditioning supply. You need to locate and take the old one with you.

Model gtdp180ed2ww. What causes it to stop mid-cycle?


Dryer runs then shuts down wont start up for an hour:
Bad motor windings


IS IT GAS OR ELECTRIC?

Gas Dryer no heat: or shuts down soon after heating CHECK:

Thermal Fuse
If the air flow in the dryer is restricted, the temperature in the heating chamber can get hot enough to blow the thermal fuse. If the fuse blows, it cuts power to the coils that control the gas valve. The fuse is usually mounted to the exhaust duct just inside the back panel. You can check its continuity with an ohmmeter. If, after disconnecting the fuse, you get any reading other than 0 when you touch the leads of the meter to its terminals, it has blown. There's no way to restore it -- you'll have to install a replacement.

Igniter and Gas Valve Coils
TEST with a multi meter: The igniter is an electric conductor that works like the element in an electric heater, glowing hot enough to ignite gas when you turn on the dryer. This conductor can burn out, and when it does, it may glow, but it won't get hot enough to ignite the gas. At times it may give a reading of continuity yet fail mechanically and not get hot enough to ignite flame though it gets hot and glows and even may show Ohms or continuity ( close circuit) ?

Occasionally, the Gas safety valve and the electric coils that control the gas valve are defective -- they can wear out when the dryer gets old. When this happens, the igniter glows, but gas never enters the heating chamber or does not stay consistant.
Performing a continuity test on either part will help you determine whether or not you need to replace it. But the coils should also be tested for amount of resistance as well as Ohms. As they may be showing ohms yet not putting out enough resistance to keep proper gas pressure flowing. Most coils should show at least 1300 ohms ( GIVE OR TAKE 150 OHMS). Anything significantly less Thus u get an ignition but then it soon goes back out. The flame does not stay lit.

Air Flow and Heat
The motor that drives the tumbler also drives a fan that circulates air through the heating chamber and the tumbler and expels it through the vent. If the air can't circulate, perhaps because of lint blockage, the heating chamber overheats, which prompts the cycling thermostat to turn off the gas. The thermostat resets when the chamber cools, but the chamber heats up quickly and the thermostat again shuts off the gas. The result is that the temperature in the tumbler doesn't stay hot, and your clothes take longer to dry, if they get dry at all.

Warning
There's a big difference between a dryer that doesn't heat up at all and one that just doesn't get hot enough to dry your clothes. In the first instance, the problem is usually a defective part, and things should be back to normal after you replace it. In the second instance, the problem is caused by restricted air flow, and you need to clear the lint filter and vents and take steps to prevent lint build-up. If you don't, you'll use more energy for drying than you need and the dryer may continue to malfunction. Worse, you may have a dryer fire.

DRYER OVERHEATING:

Heating Element
A defective heating element can make a dryer too hot. If the element partially shorts out, it can produce heat all the time, regardless of whether the dryer is calling for heat. Remove the heating element to inspect it. The coils should not be touching each other or anything else.

Other Causes and Conditions
Air Flow Problem
Dryers need good ventilation to work properly. If the vent is clogged it can make the dryer too hot. Clean all of the vent tubing thoroughly.

Cycling Thermostat
Although not common, a defective cycling thermostat can make the dryer too hot. The cycling thermostat is supposed to turn on and off the heat to maintain the proper temperature. If the thermostat is defective it may keep the heat on too long. The thermostat is not adjustable or repairable, it must be replaced.

Felt Seal
Most dryers have a felt seal at the front and rear of the drum to keep the heat inside the drum. If the felt seal is worn away or missing, the dryer may keep heating and make the dryer too hot. This is not common.

Blower Wheel
A defective blower wheel will not spin properly and will not vent the hot air, making the dryer too hot. Check to see if there is adequate airflow out of the dryer.

Dryer Overheats and or Dryer Gets too Hot

Apr 22, 2016 | GE Dryers

1 Answer

Toro porta heater only stays lit for 5 or 10 minutes then the heat goes out but the fan stays running. Re-light it and it does the same thing.


The fan will continue to run after the flame goes out to prevent the element from overheating from residual heat. It should stop after a minute or two, when the element is cooled down.

It could be a venting problem. Make sure the vents are clean. When it's not lit, air gets into it. When you light it, it slowly uses what air it has and it starves for oxygen.

It could be a misadjusted thermostat and it's turning off before you think it should. Try setting it higher and see if it runs a bit longer. My thermostat on my house furnace runs 10 degrees higher than it should, so I just keep it 10 degrees lower than it says.

When i turn the heat up sometimes it takes a long time for the gas furnace to start ..why?


Watch your furnace when you turn the thermostat up...make sure to record everything that it is doing. If you have an induced draft, forced air system, then the heat sequence of order should go like this... Initial call for heat from tstat, Inducer vent motor turns on-pulls in the pressure switch, circuit board sends power to igniter whether it is spark or hot surface, then gas valve opens. Flame sensor senses flame, burner stays on, and blower motor kicks in to heat the space. If you notice any variance from this, then something needs to be checked by an HVAC Service Tech.

Reliance 606 natural gas water heater - model #640YORT - water does not stay hot. pilot has to be clicked to heat and then u can use hot water til tank empty and it will not continue to heat water.


If I understand correctly, the pilot light is not staying lit.
You light the pilot and water in the tank reaches temperature.
Once hot water is gone, then pilot light has to be lit again.

Gas pressure is good, and gas is flowing.
Thermostat is working at high end because it cuts off heating.
Vent is working because tank heats up.
Air intake is working.

Gas control thermostat might not be reading low temperature. Replace gas control valve.
Pilot tube might be dirty. Clean burner parts and combustion chamber, and air intake, and vent.
Backdraft might be blowing out pilot. Check for constant updraft by running water heater 5 minutes, and then light match under vent hood and see if smoke goes up.
Very hot air can put out pilot, especially when water heater located in attic. Add ventilation.
Improper vent might have water dripping back down into combustion chamber and putting out pilot light and rusting out the parts. Inspect for rusted parts and water.

My Carrier 58WAV136 forced air heater's problem is as follows - Thermostat works fine, when desired temp is reached, the fan motor (blower) kicks on. Sometimes it stays blowing for a couple of seconds,...


There should be a code list inside the furnace panel access door. Find it and see what code 41 says, as I can't remember right off hand. Some of the possible causes could be air in gas line or low gas pressure. Could have blocked vent especialy if vented with plastic. Check for bird nest or dirt dobbers in vent. If vented with plastic could not have proper rise 1/4 per foot and have water trapped in pipe blocking vent. Is this a new problem or has this occured since installation?

Not heating properly, many cycles to dry loads


Check the following to address this issue--


Note: Normal drying time for a dryer is about 45 minutes (some may take up to an hour).

1. Venting
Make sure the dryer vent hose, as well as the rest of the vent duct, is not clogged.

Unless regular maintenance is performed, chances are there is a lot of lint accumulated inside the dryer. This might affect the drying time and could be a fire hazard. Make sure to have your dryer cleaned regularly. Because this might involve taking most of the dryer apart, it is recommended to have a qualified appliance repairman perform this task.

2. Thermostat
There are a couple of cycling thermostats inside the dryer. If one of them breaks down, it might affect the dryer's performance. Replace the defective thermostat.

3. Heating element
A heating element might only be partially burned out, in which case it would still work but will take longer time to dry the clothes. Replace the element if found defective.

Heat turns off


Sounds like the high limit switch on the heater is kicking off. The flash is the switch shutting off the heating element. The only way to reset it is to turn unit off for about 5 minutes. Possible problems are: 1.) Bad thermostat 2.) blower motor not turning fast enough which means motor is bad.
