Question about Ace Hardware ML250TPA Infra-Red Wall Mounted Panel Heater

Heater doesnt stay on when the temp gets colder

It seems that when the temp outside drops below 35 deg, the heater wont stay on. Also the pilot constantly flickers and will eventually go out.
Is this a tank problem or the outside regulator?
I have blown air through the pilot vent and that didnt work.
please help, its cold :(

Ventless heaters such as these have an oxygen depletion sensor that monitors O2 levels at the burner and shuts the unit off if it drops below a certain percentage (assuming that there will be carbon monoxide production). Check your owner's manual for any requirements such as a window or door needing to be open while this heater is in use.
There also is the possibility that there is water in the regulator of your propane line (if it is outside) that freezes and inhibits the regualtor's function.

I have a triangle tube challenger boiler. D.W & radiant. It has a drop in temperature about 1.5 -3 min. after turning water on. In shower and in sinks. Was able to watch tank and feel water from laundry...


A lot depends on the size of the tank. And when it heats some systems only heat at night , this is ok if the system is large , on most heaters there is a thermostat on the side that can be used to set to a higher temp. the thermostat on your heater may be faulty.

Why wont hot tub heat with jets on losing temperature on 110 volt


My first question would be about the outside temperature. What is the outside temperature?
Hot tubs that are designed to operate on 115v only have 1.5kw heaters and if the outside temperature is below 50 deg F they tend to not keep up to 103 deg water while being used. They are also designed to not heat while the high speed pump is operating.
Does it stay up to temperature on a normal basis?

Under the gas valve is a removable panel. On models of that era there should also be a second panel behind the first. remove both.

the pilot light should be clearly visible.

If no pilot, turn the gas valve to OFF. wait 60 seconds. locate the tubes from the gas valve to the pilot location. turn the valve to pilot, and with a long match or grill lighter lit, place flame at the pilot location and press down on the pilot button beside the main valve.

pilot should light. If not shut off the gas and call a technician. If yes, hold the pilot button for 60 seconds, then slowly release. Pilot should stay lit. If not, shut off gas and replace thermocouple, start relight sequence over. If pilot stays lit, replace inner cover and adjust temp to 120 deg. If heater fires up, replace outer cover. Done.

If heater does not light, replace gas valve or entire unit. Water heaters have a limited life expectancy, and if my recollection is correct your unit is 10yrs past warranty.

Lasko 5141 - I set the temp to hold @ 68 degrees at night but it seems to ignore the setting and gets into the high 70's. This is with the rotation switch on if that makes a difference. Any Help ? Thanks


Remember it is always colder at the floor level, the heater is pretty close to temp when it is above 40 degrees outside, but as the temperature gets colder outside so does the temperature at the floor level in your house because heat rises.

I use my house furnace thermostat mounted half way up the wall as a guide, When the temp outside is in the teens, I have seen as much difference between the floor temp on the heater and the wall to be 4-6 degrees different. So this means as the tempurature outside drops you need to regulate the thermostat on the heater downward to compensate for the colder floor temperatures.

Pilot light on water heater wont stay lit


The thermocouple has failed. It is the temp probe that goes from the pilot lite burner area to the control valve. Go to your local plumbng repair shop and buy one. Most appliance parts stores have them also. Take the old one with you and they will hook you up with an exact replacement. They are not that hard to change. Usually a nut or 2 screws in the temp bulb area at the burner end and a nut that threads into the control valve.
Make sure before you install the new one that the area where it mates to the gas valve is clean. Should be about a 20 min job including clean up with replacement parts in hand.

Pilot light won't light on ventless fireplace


Ventless Gas logs, Vanguard, VS30PR. Propane gas
Pilot light stays lit various times, sometimes for several days then other times for a few minutes. Lights best when temp outside is below freezing. Pilot flame appears to receive too much air. How do you adjust the pilot flame? Is this done using two screws marked A & E? Do you have suggestions?
Thanks,
Ed

Does outside temperature affect performance of freezer


Top mount refrigerator installed in a garage and the food in the freezer is defrosting when
the temperature in the garage goes below 55 degrees fahrenheit.
On top mount refrigerators you cycle the compressor and fan/fans from the food
compartment temperature. When the room temperature gets colder than 55 F, you have
long off times waiting for the food compartment to warm enough to trip the cold control.
This long off time is allowing the freezer temperature to get high enough that food can start
to defrost.
There is a kit for refrigerators installed in applications where the temperature can go as low
as 34 F and still maintain good freezer temperatures. The kit part number is 5303918301
and it contains a heater that mounts in the control box and an instruction sheet advising
how to install the heater.
Kit 5303918301 contains:
Part # 5303950194 Instruction sheet
Part # 241532101 Heater

Loss of temperature control


Is the heater staying on all the time? Most likely cause of themostat trouble is the sensor. Try to find it and measure its resistance at different temps to verify the trouble.
