Furnace shuts down before heat temp meets thermostat. Furnace unit starts frequently. Service installed new limit switch and a new circuit board but furnace unit continues to malfunction. Same problems...


has any one checked your thermostat. as soon as the furnace shuts down then turn up the stat and see if it starts right up. i would think the stat function should have been checked also.

We just installed a honeywell thermostat, our furnace is an old furnace and now it won't shut off. it is a hot air oil furnace. any suggestions


for a quick test -- remove the wires from the thermostat and see if the heater shuts off then,,, if it does shut off then the problem is the type ( model ) of the thermostat and it may not be compatible with that heater or there is something wrong with the way that the thermostat is wired. ( make sure that the thermostat is reading the correct temperature and is in fact in the off position ). also double check the wire color code at the heater and make sure that the right wires are connected proper.
what model is the thermostat ?

The Goodman Heater was installed in 2004. Thermostat set at 75F, the fan that blows CO2 out was on for about 1 minute, then I could hear the sound of the gas blowing into the furnace, but the ignitor...


Problem: Your furnace will not ignite the gas to produce heat for your home. When a furnace has a bad ignitor what I see most of the time is the following sequence of operation:


1. Thermostat calls for heat. 2. Draft inducer motor starts. 3. Pressure switch attached by a small plastic or rubber tube senses the negative pressure produced by the draft inducer and closes. 4. Draft inducer runs for 30 seconds to a minute before you hear a gas hissing sound. The ignitor did not glow, the flame sensor (a small metal probe about 1/8" in diameter, with a white porcelain base) does not sense the flame, so after 8 to 10 seconds the hissing sounds stops with no ignition of gas to heat your home. Your furnace shuts down and goes into a lock out condition until you turn your power switch back off and on again. Then the sequence starts all over again with no ignition of the gas. Solution:You probably need to purchase and install a new ignitor. I would suggest that you inspect your ignitor closely for cracks. Make sure you do not touch the ignitor with your bare hands. If you do not visually see a crack, then you could have a furnace control board problem or a limit, rollout switch problem. The furnace's control board might not be supplying the voltage to the ignitor. If your furnace lights and the gas stays on for 8 to 10 seconds, then shuts right back off, then you need to clean your flame sensor with light sand paper or steel wool. You might need a new flame sensor, but most of the time they can be cleaned an will work well after cleaning.

My furnace keeps blowing fuses why it is a nordine model #e2eb-015ha


The first thing i would do is shut off all the power to the unit and disconnect all the wiring from the thermostat. then i would install a jumper wire from R to W on the circuit board and see if the furnace runs good. if it runs good and does not blow a fuse, your problem is in the wiring between the t-stat and the furnace. If this does not help, please indicate if your system is a straight a/c, furnace system. or if it is installed with a heat pump. also does it make any difference what the temperature is outside. for example, does the fuse only blow when the temp drops down into the 30s or does it not make any difference.

Furnace will not shut off after the setting is reached. have changed thermostat. Temperature reading goes down on thermostat, furnace still runs. Model : Goodman furnace,gmh95/gch9


Check if your thermostat is set on 'o fan' setting.
If it is, trey to set it on 'Auto-fan' instead.
since it seem as if the heating does go off,only the fan may be running continuously.
this is possible if the thermostat is incorrectly set or installed.
good luck.

RHEEM OIL FURNACE MODEL ROBD 067 LBEA BLOWER


You will likely need to install an isolation relay in the W circuit from the thermostat. Some thermostats rob a small current through the W circuit to power the thermostat. This small current can be enough to start the fan circuit timer. You can test this by disconnecting W at the furnace and allowing the timer to shut down. If the fan shuts off with the W disconnected you can install a simple relay.

The relay coil will be connected to Common on one side and the W from the thermostat to the other. Then you will run a wire from R on the furnace to the relay and from the N.O. Contacts to the W terminal on the furnace. This will kill that signal that is starting the timer and the W can steal it's power through the coil back to common.

Furnace blower not working how it should


first off buy yourself a honeywell stat, in my personal opinion lux stats are garbage, I have run into so many that are bad stats !!! but as far as your fan not shuting down, sounds to me like your fan center on your circuit board is bad and will not shut down the fan when needed, you will have to replace the circuit board, as the fan center is a part of the whole of the circuit board, hope that helps

Room temp is not where it should be before furnace shuts down


Did the installer check the amperage at your thermostat and then adjust the heat anticipator? Or you may need to have the blower time settings changed to suite your needs. Get them back in to check.
