    Doesn't have pressure switch. Forgot to say it runs a few hours then locks out, and I reset by turning power off and unplugging exhaust motor and it resets for a few hours

My furnace has error code flashing 3 flashes How do i correct this problem


check inside blower door to see what the code means.there should be a sticker with that information.if it is a code for the power vent switch make sure the tube is clear and tight and the vent has no obstructions.you may be able to temporarily jump out the switch to test but DO NOT bypass it permantly!You may have to clean or replace the inside of the switch with a small drill bit or something similar.In any case the codes should be listed to help you.

Intertherm furnace model # MMHB-070ABHR-06 red light blinks two times


Number of flashes mean different things for diff models. The meanings of those flashes should be posted somewhere on the unit; usually inside front of the bottom service panel. Though you can't truly diagnose a problem by number of flashes they can give you an idea of where to look for a problem. There are a ton of videos and how-to's about furnaces on youtube by real service techs. Most modern furnaces have basically the same set-up and features so don't worry about your paticular brand; but of course that would be the best place to start looking. You could start here to familiarize yourself with your brand of furnace:

Sounds like the thermocouple has gone which can happen any time nothing to do with reg change But I would check that pilot is not blocked causing a short pilot .

I have error codes flashing on my thermostat..it is an american standard model the manual for the therm. has ACOT900AC43UA on front..says to find addedum 18-HD32D2-1/69-2009 for codes i cannot find it...


Error codes from American Standard Pub 18-HD32D2-8, which is a one-sheet document that came with my American Standard air-conditioner:

29 = not listed

129 = not listed

80 = HPCO Fault - problem is in outdoor unit - Desscription: High Pressure Monitor Fault (hard lock out, cycle power to reset)

91 = Communication Inactive Fault - problem is in air handler - Descriptions - COMM Bit Master Clock Error, COMM Heat/Cool Demand Error, Serial Motor Communication Inactive Error

91 = Communication Fault - problem is in furnace - Descriptions: Blower motor no COMM response, Inducer motor no COMM response, Loss of heat/cool demand, Loss of clock signal

91 = Communication Fault - problem is in outdoor unit - Descriptions: Loss of Heat/Cool Demand Message (COMM), Loss of Bit Master (Clock Signal)

91 = Communication Fault - Description: Comm line is dead and no bits have been received.

By the way, I do not recommend American Standard. I've had mine 14 months and it just blew up - the entire control panel blew. My advice to you - think about a different brand.

Carrier Gas Furnace runs fine randomly stops blowing LEDs flash


That blinking light may be the diagnostic light. Count the blinks next time it fails. Carrier units will have two different blinks depicting the error code such as one blink followed by a pause than 3 blinks giving you an error code of 13. Then look at the wiring diagram, it will have an error code chart telling you where to start with your diagnosis. You already know that if you remove the cover it erases the error code, so look thru the small window first.
