My TL heater series 2, model ESC keeps kicking out after 5 minutes of heating..then kicks back in heats some more.. then repeats on and off cycle

Hi,

The heater is made to heat up to 1000 square feet. so if you're in space larger than this, it might not be able to sense the proper temperature as the area around the heater is not at as high as a temperature as outside.

To compensate for this, you might want to set the limit at 30 degrees below it's target. If things continue as they are you can attempt a factory reset.

Thank you.

Unfortunately that means there's a hole in the heat exchanger, particularly in that cell of it. When the main blower comes on the air is pushed into the heat exchanger, causing the flame rollout. A heat exchanger crack or blowout is usually what condemns a furnace for good. Goodmans however, have a lifetime warranty on their heat exchangers, so you'll probably be able to find someone to replace it pretty cheap, or do it yourself for free.

Whats' so hard is the Honeywell thermostat has a built in 1@ differential. It is not adjustable.
You might ask your installer about a time delay relay installed in the furnace to break the thermostat heat wire (usually white wire).
Most time delay relays are 90 seconds. But that might be enough to reduce the furnace cycling.

Check the thermostats. They work when cold but will not reset once warmed up.

Hi sounds like the pressure switch is faluty try jumping out to see if it starts

check your heat antisipator setting make sur eit matches your tpye of heat. also, do you have a 2 stage heating sys?

These heaters are the same as the marley heater, the element never gets red hot. the unit is set up so the fan kicks on after the element has heated to a certain temp and turns off after the element has cooled. It is common for these heater fans to cycle on and off quite often untill the air temp reaches about 55 degrees and then will operate normaly. If the fan still cycles too often you may have to replace the fan control and high limit switch. These are not very expensive and easy to replace yourself. they arte usualy attached to the back of the element with clips. The luke warm air is what these units put out. I have an equivelent to the dayton G73 and it heats a 24' X 30' garrage all winter in central Minnesota.

chech the air filter is clean and the fan limit switch look to change fan limit

Honeywell heaters like HZ3650 have a screen on the air inlet at the back side of the heater. This screen can be partially blocked off by an accumulation of lint, etc. The lint blocks some of the air flow which may cause heat increase within the heater to the point that the safety shutoff thermostat shuts off the power. Operation is returned after a cool down period only to repeat the shut down cycle after a short period of operation. If this is the cause of the problem the screen must be cleaned.
