These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure. http://electronicshelponline.blogspot.com/ http://electrotechnician.blogspot.com/ http://homenol.blogspot.com/
Code 41= blower out of valid speed range. you will more than likely need a new motor module. they are not cheap 300$ to 400$. If you call a carrier or bryant tech out they should have a test module they carry on their truck that lets you know if its the furnace circuit board or motor module.
code 33 LIMIT OR FLAME ROLL-OUT SWITCH IS OPEN - If open longer than three minutes, code changes to #13. Flame roll-out switch requires manual reset. Check for: - Dirty filter or restricted duct system. - Loose blower wheel. - Defective blower motor or capacitor. - Defective switch or connections. - Inadequate combustion air supply (Flame Roll-out Switch or fuse link open). - Open Flame Roll-out switch, or fuse link. Manual reset or replace.
There are several possibilities, the drain valve is opening and closing, this causes water to fill the base, the float valve will not achieve the desired level so the fan will not start. This could be the drain valve actuator is U/S or the PC board. Have you tried to turn the main power off at the switch board for 1/2 hour?
Most occasions the service person will swap out all the units as they purchase it as a package. It is not cheap to replace these units.
Most Bryant units do not have a reset button but could have a low pressure or high pressure switch for a safety to protect the compressor. Verify power from the thermostat to the contactor by following the thermostat wires all the way to contactor inside of electrical compartment... TURN POWER OFF BEFORE OPENING.... If power is to contactor and contactor is pulled in then you would need to look at the capacitor of which is a canister about 6 inshes tall with wire terminals on top.. this part should be flat on the top and if it is rounded then thats your problem.. if not then contact a local company to troubleshoot and make necessary repairs.
'Limit or flame rollout switch is open'. In my case, the flame rollout switch had tripped due to an overheating? I had to push the button between the wire leads to reset the switch. Then when I turned the power back on, the furnace started up like normal.
Why did the switch overheat and trip? My current theory is that there was a rubber grommet around a pipe near the switch that had slid down and was no longer sealing the furnace?
as a general rule the lemon law does not effect acs. because the equipment colud be at fault, or the installer couild be at fault , or the installation or application coiuld be at fault, or the power company could be at fault or the ductwork inadquete or undersized? so there are so many variables that a new ac may not fix your problem so they rarely ever provide new.now lets discuss your insatller or dealer. why are they saying the rev valve is bad? let me say covs Changeover valves usually do one of three things. they stick in cool and wont shift so youare stuck in cool or sruck in heat. when energized you hear no kawhoosh sound and compressor doesnt change pitch. then they are stuck in heat or cool. what they do sometimes is stick halfway and that gives a coolish suction and a coolish line to the house but not real cold. the hot gas line is only warm and the discharge line is onlty warm. this means its stuck halfway. some times you can disconnect the fan run the pressures way up and gently tap the valve and it will free up. but it nay stick agagin. the valves in the compressor may also be weak and be misdiagnosed as as half stuck covalve.. you could close off the liquid line and see if the compressor cah pump down to zero . if it can't then compressor maY BE BAD .when the unit was installed did they put in a liquidline drier to collect impurities and protect the valve? its pretty unusual to see a valve fail and if to much heat is applied on replacement then new valve can be damaged. good luck , oh you have the option of requesting a different dealer if it is brand name like trane or american std with a parts and labor warranty. most dealers can honor the other guys warranty and get paid by the factory if you have lost confidence in your guy. i am sure you know right away if you got a budget jack leg job or a pro . good luck.
If your unit has a thermo-coupling this is most likely the issue This little sensor sends a milli-voltage to the gas valve telling it to keep sending gas for the pilot since its lit and all is good. They wear out and the gas valve thinks the flame has gone out (whick is hasnt) and kills the gas flow.
