20 Most Recent Dyna-Glo D-E37 Wall Mounted Panel Heater Questions & Answers

If you don't know that I would recommend calling a plumber or the gas company when playing with natural gas heaters tour safety is is not worth trying to save money a qualified technician is highly recommended do not attempt to repair it yourself if you have no experience in that field your family and your life is at risk!

sounds like a blocked pilot when you turn on the main gas takes the gas away from the pilot and goes out

it s the thermocouple excannge it should solve the problem , try national energy they do spares

You must hold the button down long enough to heat the thermocouple in order for it to stay lit.
Hold it down for a full minute after lighting, if this does not work then take some compressed air
(this is sold at office supply places to blow off keyboards,etc.) and blow the thermocouple clean of any dust and retry the lighting procedure. If this does not work then the thermocouple will have to be replaced.

If your heater is no more than 6 years old and hasn't been cleaned and serviced annually, it's probably a case of the Oxygen Depletion Sensor (ODS) being clogged with dust, lint, spider web or pet air. Therefore, the ODS reads the oxygen level in the room, as unsafe for operation and doesn't allow it to light and hold.

You can clean it yourself by removing the front half of the heater cabinet after turning the gas off to the heater.

You'll need a vacuum cleaner that has a hose and brush attachment (a shop vac works real well).
a can of compressed air with a straw nozzle (like you clean your computer with) and a flashlight.

Once the front half of the cabinet has been removed and set off to the side. You will have access to all the inner workings of the heater. Plus, if it hasn't been serviced annually, you find a lot of dust and lint. Carefully remove the Ceramic Plaques (if it's an infrared heater like you picture) and set them off to te side out of the way.

Using the vacuum with a hose and brush attachment, vacuum all of the interior (including the burner(s) that you can safely reach. If your heater has an optional blower, vacuum that too.

Once the vacuuming is complete, take the can of compressed air with the straw nozzle attached and blow out the pilot tip where the flame comes out. With a flashlight, look down the pilot assembly from the pilot tip and about 2/3rds of the way down you will see a small hole in the side of the pilot assembly. That's the ODS sensor. Place the tip of the straw nozzle just barley into that hole and hive it a quick blast of air. If you watch closely, you will see debris fly out the other side.

Now, take a look at the Thermocouple. If it's a stand-a-lone thermocouple (Brass rod that sticks up in front of the pilot tip), does it look ashy or white? If so, take a strip of very fine sandpaper or emery paper and polish the thermocouple. You don't want to sand it down ... just polish it. After completing that, take a cotton ball dipped in alcohol and wipe the thermocouple tip off.

Before reassembling the cabinet, turn the gas back on and try lighting the pilot. It probably won't light the first time, because there's air in line from the gas line shutoff valve to the heater. If it doesn't relight immediately, hold the control knob down in the Pilot Position until you smell gas. Let off and wait 5 minutes, before trying to light the pilot.

If the pilot lights and hold after you have held the Control Knob in for one minute. Ease of the control knob and turn the knob to the ON position. The burner should light. Take note of the flames and their color. They should be Blue with Yellow tips. And the burner flames should be coming from all the little burner ports (holes).

If it all checks out well, turn the heater off, allow it to cool and reassemble the cabinet.

Hope this helped you. Please let me know.

I do not know how many times people will wander into my shop wanting to buy an expensive thermocouple only to get home and have the same problem as before. Don't spend any money till you try this: Clean the pilot safety. Blow it out with shop air or a straw or flush it with rust buster but do not mess with the flap on the pilot or you will ruin it. I use the rust buster to flush the dust and cobwebs out of many a heater. I wrote a page and included photos HERE

Those thermocouples are built quite well. I have not ever seen a bad one.

What's the pressure to the heater? It should be a minimum of 11 to 13 water column inches. Also, make sure that your heater is in fact a propane fueled heater. Don't go by whats on the box it came in. Look at the manufacturer's tag(s) on the heater. It may be a Natural Gas unit instead of Propane unit. I've seen this happen before. In which case it won't work and can not be converted.

Yes, it is a safety shutoff. More than likely the Oxygen Depletion Sensor (ODS) is clogged with dust, lint or pet air.

To clean it, turn the gas line feeding heater off. Remove the front part of the heater cabinet. This will expose all of the inner workings. You'll probably find a lot of dust and lint, so use a vacuum cleaner with a hose and brush attachment to vacuum all the areas you can safely reach. Do this gingerly. Look for the Pilot Assembly (it won't be hard to find). Using Canned Compressed Air and the Straw Nozzle (Like you clean your computer with) hold the can as upright as possible and place the straw nozzle just into the tip of the pilot. Give a quick blast of air. Now, look down the pilot from the tip and you should see a hole in the side of the pilot. That's the ODS. Place the tip of the straw nozzle just barely into the hole and give it a quick shot of air. That will blow out any debris.

Reassembly the cabinet, turn on the gas line, purge the air from the line by pushing the control knob down and holding down for several minutes. Let off the knob, wait 5 minutes and try lighting the pilot. If it does light immediately, there may still be air in the line. Continue to try lighting until you get a pilot flame. Hold the Control Knob in for at least a minute, slowly let off. If the pilot stays lit, turn the Control Knob to On. That should solve your problem. If it doesn't, you may need to replace the thermocouple.

This means that it is porbably the flame sensor/thermocouple. You can clean this off with some steel wool and it should solve it temp. but it will need to be replaced.

It would be ideal to take it apart and blow it out but you could try vacuuming out the grates real good. If you need further help, reach me via phone at https://www.6ya.com/expert/dan_73bbd84fe1d95b61

The orifices for a propane heater are much smaller so you will not be able to get the natural gas to flow properly with the current orifices.

The both the natural gas and propane valve are 1/2 psi so the valve can be used but the regulator for propane is typically 8-11 inches on the wc table and the natural gas is typically 3 lbs on the wc.

You may be able to drill out the orifices in the burner and in the pilot ods and get the unit to work.

I'm not familiar with these heaters but I assume there is button or something you push to get the pilot to light. There will be air in the pipe between where the gas comes in and the pilot light. You have to give it enough time for the gas to push this air out of the line. Hope this helps.

Hi did the purge the line you could have air in it , it will take ages to come out of the pilot

Almost any hardware store carries thermocouples and thermopiles. Take your old one with you so you get the right length.

Before you attempt to covert to lp. You need to check the flue. Black smoke is cause by incomplete combustion. So it may be now plug with black soot. Heat-exchanger may be damage Before you invest in a lp kit. Make sure it is worth it. To convert you need the main burner orifices and lp spring for gas value. Once you replace these parts you must adjust gas pressure, nat gas is measured at 3.2 - 3.5wc lp is measured 10.5 - 11.00 wc. In my honest opinion this is to dangerous for customer to attempt. Please a HVAC contractor inspect unit and install lp kit.

First of all you must be very careful with working with propane, unlike natural gas,propane is heavier than air and will not dissipate. Coupler (Thermocouple) There many different types, But what they all have in common is the tip. The unit may have what they call a pilot. Most customers know it as the pilot light. once you find the tip in the pilot in the following picture is a type of thermocouple. look at the tip. Then look at yours Follow tip assembly it should be attach to what we call a gas value

pilot tube/jet is probably blocked
