Question about Procom ML300HGA Heater

Open Question

I have a ProCom MD200TBF space heater that is 3days old. Ever since installing it the blower comes on when set to auto & the pilot/burner goes off. I turn the blower off & the heater stays on.

I had some look at it, they don't know why. The blower is fully enclosed, no settings to set. I talked to Lowes, they don't know either.

SOURCE: Pilot goes out!!

My manual shows three possibilities:  1) Insufficient fresh air available for combustion, so ODS kicks off gas flow 2) Low gas line pressure (should be between 11 and 14") or 3) ODS/Pilot is partially clogged.  Toll free number for ProCom is 877-886-5989.

SOURCE: heater will not stay lit on auto procom ml 300 blue flame

If you have an ML300HGA, it is a manual-control heater, which means you turn it on and you turn it off. No thermostat. It does not have an AUTO setting.

Likewise, the thermostat-controlled models do not have a Manual mode. If you have the ML300TBA, it has a thermostat and will turn itself on/off in order to maintain a room temperature.

On manual models, the numbers (if any) on the dial are heat output selections. Set the control to the highest heat setting and that's what it does until you turn it off.

On automatic thermostat models, the numbers on the dial are temperature selections. Set the control to the highest heat setting and the heater will continue running until it is 85-90 degrees, then shut off. Set it around 2 and it will maintain a temp of around 70 degrees.

All Procom heaters are either automatic (thermostat-controlled) or Manual. None are both.

I have set the times for the heating to come on and put it to auto but it doesnt seem to come on at the times i've set it at??


If the Procom Model number you referenced is correct, this heater does not have a automatic timing feature to turn the heater On and Off. However, it does have a built-in thermostat control, that turns the heater's burner on, once the room/area drops below the temperature/comfort level you have set it for.

Conversely, it turns the burner Off once it reaches and holds the temperature/comfort level for 5 minutes or more, it turns the burner OFF, again. Keep in mind, because this is a built-in thermostat, it's reading the air temperature closest to the heater.

If the thermostat feature is what you're having a problem with, it may be that the sensor bulb has failed (assuming it's not turning ON & OFF automatically). However, this is a fairly rare failure. Unless, the heater is very old or hasn't been cleaned and serviced annually.

Another situation would be that the Control Knob has been left in the PILOT position, rather then the ON position. If that is the case, the heater will not turn ON, period.

Right now, your Owners Manual is your best source of information on the correct operation of the heater, as well as it's Trouble Shooting Guide.

If you have misplaced the Owners Manual, here's a printable link to it. Just locate the Model Number of your heater, ML300TB and click on the icon to the left of it.

I have a PROCOM model ML300TBA, two years old. Here is my problem: Pilot lights fine. Burner lights fine. When I go back the next morning, often times it is out. Burner and pilot are out. It will...


You could try cleaning up the thermocouple with steel wool. Some manufacturers call this a flame generator as well. Any how make sure it is clean and positioned in the top center of the pilot light for best signal. This is only speculation as these are common problems that will arise on heaters in general. This also turns the gas to the burners and pilot light so thats why to start here first. Hope this helps you out.

My pilot light ignites but when you turn the knob to light the burner it goes out?


Your pilot generator may be the cause. They tend to get weak and will hold the pilot but won't be strong enough to operate the gas valve solenoid. All space heaters have some sort of thermocouple device in the pilot that hold the gas open as long as the pilot is lit. Some simply hold the gas valve open while others called millivolt valves use a pilot generator to operate the solenoid. Another type of heater is an ODS type. This system has a oxygen depletion pilot safety feature. When oxygen gets low the pilot shuts down the gas. If this is what you have then all you need to do is blow the dust out the pilot and it should stay on.
