Each of the following status codes is a two digit number with the first digit determined by number of flashes of the yellow led and the second digit determined by number of flashes of the green led.


Like many furnace manufacturers, Bryant uses flashing LED lights to indicate error codes that can give you an idea of what's wrong with your furnace when it's not functioning properly. The short flashes indicate the first digit of the two-digit code, and the long flashes indicate the second digit. Here's are some common error codes.


CODE: RED LED1 ON.
RESULT: Furnace is operating in emergency heat.

CODE: RED LED2 ON.
RESULT: The microprocessor has malfunctioned. To reset: Put setup switch "SW-1" in the "ON" position nad jumper thermostat terminals "R", "W/W1" and "Y/Y2" simultaneously with the door switch pushed in and power to the unit "ON". Disconnect jumper and place setup switch in the "OFF" position. If LED2 reappears, replace main control board.

CODE: YELLOW LED3 ON.
RESULT: Furnace is operating in high heat.

CODE: GREEN LED4 ON.
RESULT: Furnace is operating in low heat.

CODE: RED LED2 FLASHING.
RESULT: Line voltage polarity is reversed.

CODE: 1-1.
RESULT: NO FAULT IN RECENT HISTORY DISPLAY
FIX: Indicates no faults have occurred within the last five cycles. To read recent fault history, put setup switch "SW-1" in the "ON" position. To clear recent fault history, put setup switch "SW-1" in the "ON" position and jumper thermostat terminals "R", "W/W1" and "Y/Y2" simultaneously until an "11" is flashed.

CODE: 1-2.
RESULT: BLOWER CALIBRATION LOCKOUT
FIX: Indicates RPM calculated for low heat was less than 250 RPM or greater than 1300 RPM on two successive attempts. Auto reset after three hours. Reset power and refer to fault #44 section.

CODE: 1-3.

CODE: 2-3.
RESULT: INVALID BLOWER AIRFLOW SELECTION
FIX: Indicates improper "A/C" or "CF" switch setting. The 042 and 14 units can deliver 1-1/2 to 3-1/2 tons A/C and 600 to 1400 CFM for continuous fan. The 060 and 20 unit can deliver 2 to 5 tons A/C and 800 to 2000 CFM for continuous fan. If code is flashing, unit will default tp closest allowable airflow.

CODE: 2-4.
RESULT: SECONDARY VOLTAGE FUSE IS OPEN
FIX: Check for: - Short circuit in secondary voltage (24VAC) wiring.

CODE: 3-1.
RESULT: PRESSURE SWITCH DID NOT CLOSE OR REOPENED
FIX: If open longer than five minutes, inducer shuts off for 15 minutes before retry. Check for: - Excessive wind - Proper vent sizing -- Defective inducer motor - Low inducer voltage (115VAC) - Defective pressure switch -Inadequate combustion air supply - Restricted vent - Disconnected or obstructed pressure tubing - Low inlet gas pressure (if LGPS used) If it opens during blower ondelay period, blower will come on for the selected blower off-delay.

CODE: 3-3.
RESULT: LIMIT CIRCUIT FAULT
FIX: Indicates a limit, or flame rollout is open. Blower will run for 4 minutes or until open switch remakes whichever is longer. If open longer than 3 minutes, code changes to lockout #13.

CODE: 4-4.
RESULT: BLOWER CALIBRATION FAULT
FIX: Indicates the calculated blower speed is below 250 or above 1300 RPM. Unit will default to low or high heat mode if possible. If this fault occurs in conjunection with fault #41, check wiring to motor otherwise refer to the trouble shooting guide. If this fault occurs by itself, check for undersized ductwork, or excessive static caused by a dirty filter, or closed registers.

Had new furnace installed and ran into some difficulties but the contractor responded in a timely and efficient manner - after further service calls were made, a reasonable resolution was found.

by Brian Burns, Whitby on Twintech Heating and Cooling

The work was done quickly efficiently neatly and professionally. Pleased with the service, information, product, and the company.

by Geoff, Port Perry on Twintech Heating and Cooling

Great sales member named Dave came in told us some amazing items and how they would be priced installed an all. We couldn’t believe it! The next day the ac was installed, that day one employee named Greg told us that our furnace was working way to hard and was causing us to use way too much gas. So two days later they came in an installed a new furnace!

by MB, Ajax on Twintech Heating and Cooling

Installation was done quickly and professionally. The new furnace is quiet and provides even heat.

by Richard from Oshawa on Twintech Heating and Cooling

They removed and discarded old furnace. Installed new furnace. Installed air intake pipe, that had never been installed by builder, no charge. Replaced loose hose on floor with hard pipe and rerouted it to drain, no charge. Almost 33% cheaper then quote from Enercare, which was the company we dealt with and had insurance with for 8 years. No yearly fee for cleaning/insurance, saves 300 a year. Courteous, professional, fast, and friendly. My wife and I have been recommending them to everyone we know and meet, and will continue to do so. Thanks for everything, Twintech!!!

by Darcy from Pickering on Twintech Heating and Cooling

This company was great to deal with. Our furnace went down and they installed a new furnace the next day with a lot of professionalism!

by gillian hooton from Uxbridge on Twintech Heating and Cooling

Finally! An honest company with highly knowledgeable and informative staff. Had a furnace service and found multiply errors in our system from an amateur installer. Very fair price to correct problems and will definitely use again.

by alisiena from Toronto on Twintech Heating and Cooling

Fantastic team. Completed the job as per the specifications and in under 3 hours. Highly recommended Twintech.

by David from Toronto on Twintech Heating and Cooling

During the summer, I previously hired TwinTech to replace my air conditioner when it failed. They did an excellent job so when I decided to proactively replace the furnace I contacted them. The furnace I had was 22 years old and showed signs of internal leakage. It still worked but rather than wait to have it fail in cold weather, I decided to purchase a higher efficiency model before it failed and take advantage of energy efficiency rebates. TwinTech offered very useful advice on the make and model of furnace to choose including high efficiency and variable speed motor. The price was reasonable, TwinTech arrived at the allotted time, installed the new furnace (including some re-routing of exhaust lines since the existing ones were too close to other vents), removed the old furnace, tested the installation and cleaned everything up. Overall, it was a good experience, they did a great job and the new furnace is working well.

We were new homeowners in need of a second opinion. TwinTech Heating & Cooling were Amazing and professional. Very knowledgeable and great service all around. Recommend to anyone looking for honest and reliable services. Treated with respect and care. Thank you Greg, Mitch and Bob!

by Ruth on Twintech Heating and Cooling

TwinTech is an excellent and honest company! I called them for a second opinion after being told by another company that I needed to replace my furnace. Turns out this was not the case at all! I did not need a new furnace. TwinTech did not push to make an unnecessary sale and saved me from a huge expense. Bob and Mitch were extremely professional and above all honest! I definitely recommend TwinTech!

by Anna Chin on Twintech Heating and Cooling

Amazing experience with TwinTech Heating & Cooling! Their team was professional, knowledgeable, and efficient from start to finish. They installed my new furnace quickly and left everything spotless. The technicians took the time to explain everything and made sure I was comfortable with the system before they left. Great customer service and fair pricing. I highly recommend them for anyone needing HVAC services!

by Connor Agnew on Twintech Heating and Cooling

Great experience all around. Bob was sharp and easy to talk to, and Greg handled the installation perfectly. Would hire them again in a heartbeat.
