Hello elanalex,
When your heater shuts off it trips your main breaker and that is usually associated with the interupt capacity of the breaker ( which means that while your heater is drawing current, if the thermostat says stop.. you are interupting that current demand abruptly and your getting a surge back to your breaker, You may be able to add a surge arrestor to that power feed to suppress that problem. You may also be able to repsecify your main breaker with one that has a higher interupt capacity.. Check with a local electrical supply house..explain the problem and they should be able to provide a hardware solution. Make sure you provide details on your circuit breaker brand so they can provide the proper solution.. GoodLuck
Regards,
Rick

Fan runs and it wont ignite


Hi, when a fan runs on a unit before ignition it is a sign of a lockout. One or more of the lomit switches may have been tripped. Here are some sugestions to try.
1. Turn thermostat down all the way.
2. Turn the power off to the unit.
3. Wait 5 mins then turn the power back on and then the t-stat 20' above room temp.

Most units have a small inducer fan and a main blower which circulates the heat through the ducts. If the main blower is the one coming on then more than likely a limit switch has been tripped.

A limit switch (some units have three to five) is a small circular metal unit screwed to parts of the furnace. It normally has two low voltage wires going to it and a small (Really small) little pop up breaker . Locate them and just try pushing the button, if you here a click then you have rest the switch (As long as it does not continue to pop you can call it a freak and and enjoy the heat, however if it continues to trip any number of problems could be the cause of it.

Hope this helps, contact me if you need more help.

Only large flame comes out and fan does not start


Since this is a propane unit, do not turn it back on again without the fan working. First check to see if the unit has a pop out style breaker, reset it if popped. Check to see if you did not trip a breaker at the breaker box.

Try turning off the thermostat, and the curcuit breaker for the Furnance isside the Breaker box, wait about 15-20 minutes and turn the breaker back on, this should reset the thermostat and clear the lock-out, and you should be able to obtain heat, if the Furnance is displaying a code you will have to find out the meaning of the code and do the necessary steps on the furnance cover under troubleshooting.

Honeywell t8000c display is blank, unit doesnt run


I would say that you have one of two issues. Either your thermostat is bad or you do not have 24v coming from the heating unit. In this case the problem would be in the low voltage circuit of the heater. At the heater you should have 24v AC when you place an electric meter across the R terminal and the C or W terminal. If you have no vaoltage across the R to either the C or W then you have a bad transformer or a blown fuse in the furnace. If you do have voltage ther and also at the t-stat then the t-stat has gone bad, replace it.

I have a Daton Fuel trimmer furnace for my garage.


On the thermostat see if it has a setting for fan on auto and off try turning the fan on then see if it comes on, if it does then it may be your thermostat has failed if it does not turn on then reset the circuit breakers to see if you have a breaker kicked off. If it was wired properly there should be one near the unit and one in the main breaker panel so be sure to reset both. To do this you must force the breaker switches all the way off then all the way on. On some breakers if you do not force it to the off position it will not reset the breaker. If this does not help let me know and I will try to help you some more just replay to the e-mail you get go to the bottom of the page and post add comment

Central a/c and heat not blowing not working


Could be a circuit breaker tripped. Check the electrical panel for a tripped breaker. If they check out, then call a service tech to look at the outdoor unit. Good luck

Need to know which terminals run what


Had similar problem, continuous fan, turn off power, then won't start up. Replaced thermostat, no change. The main controller board in the furnace went bad. What was weird was that it happened in the summer, while the heat was turned off. One day I noticed that the fan was running. The thermostat was in the off position, and I had to shut off power to the furnace to make it stop. I forgot about it till heating season came along and it wouldn't start up. The preliminary blower would start, the gas would click on, it would light, then quit. After tracing and checking the various safety switches, etc. it became apparrent the main board was bad. I found one on ebay, replaced it, [a simple job, unplug, a few screws, replug] and it's been working fine..good luck, John
