it is a backward incline

Deminimus release

Fan proving switch possibly, cold supply air causing condensate in sense tubing. Relocate switch higher than pick up

Shift then unit test, push and hold service button until lite stays on simple. this to cycle thru operations. Unit test and same to check individual fans

Those screws holding the dome on should be tightened along with everything in the combustion blower end around the heat exchanger at scheduled service visits. Along with incoming and regulated gas...

Started at 43 graduated at 47 years old. Best decision I ever made.

Huh imagine that.

On a call for heat,during spark ignition,the spark generated by the ignition probe may cause an excessive amount of electrical noise to be induced back into the RTRM module,this noise is then passed...

I

CTI is what u need

Sounds like somebody cycled power and wala?

Install a grounding strap from board to structure. Problem solved

Id say its most likely a flame rod issue. What's your flame sense at pilot pressure?

Trane has what you need. Call Trane Supply

I agree .Sounds like your crossover slots are full of rust. Use your utility knife to clean out.

true dat

sounds like internal check valve is stuck.Get a BFH and 2x4 and give it a whack.

Sounds like no one has been cleaning condensate lines ever to cause such an issue to happen.

Epoxy is only a temporary repair until a new coil is purchased

Pull the access panel off the economiser hood and verify actuator operation. Also red service lite should be on on uem board. When putting in test mode and nothings working, disconnect the j6 plug on...

Supply air sensor is the problem.Get new SAS or pull OAS and use it.

Just shut down ckt 1, to dang cold out with windchill at -17* f. Will return at end of week to investigate. Customer happy and occupants in office below condenser happy with noise gone .

OAT 8*. head pressure control making a loud vibrating noise. Is this a sign of internal damage to the valve or diaphram or is it common at this low of ambients

Use existing back support under HE, use new bolt that comes with new unit. Most come with inducer and gas valve if ordered. 1 guy for 4 hours, 1 guy for 8 hours.No crane needed to remove and replace,...

2 guys, 1 for 4 hours and 1 for 8 .No crane needed to install , maybe to get on the roof.

Does the pilot lite? then go out. IGnition control board

I wonder if the occupants getting headaches had anything to do with this stupid repair. Must not own any red tags

Had same problem with a unit heater. Copper cleaned, still wouldnt take. Picked up some Silvabrite 100 solder and wahlah, 95% tin 5% silver, problem solved. Stay away from water based flux.

Pull the J7 plug off the UCP .Check your DC voltage from J7-2 and J7-9.Apply power and jumper LTB -14 TO LTB -5. Should read 2.8 VDC for heat stage 1.LTB 14 TO LTB 3 HEAT 2 should be 3.71 VDC If the...

I dont know if you meant -.2 I.W.C. , but thats the spec on that unit.

Anyone with info on where to get a IOM for MODEL CFA-220.

The new impellers come off really easy . Just remove the dome nut. Most pull off .Havent had to use a puller yet

Water and dirt makes mud. You have to separate the split coils on the condensers.You will be surprised.What looks clean on the outside is most likely hiding enough cottonwood to knit grandma a...

Looks to me like your insulation on the HE access panel is resting on that particular tube causing a hot spot.

What LED's are on when the failure occurs on the flow sensor and also what color is the flow proving sensor.Also what is the position of the black dot on the flow sensor.All very important for...

If the system is tripping after a short while, check the overloads on the compressor circuit breakers, they come from the factory set to zero, raise to 4 on all compressor c/b.'s, happened to me....

Why not just raise the cooling setpoint on the individual vav box to please each zone thats an issue. This can be done in Tracer.

hold the self terst button in on the bottom of the sensor for 2-3 secs. t i think this action resets the sensor.

pull the j7 plug and check terminals j7-8 and 11 to ground for 5 vdc. if not the ucp board is bad

i suggest testing the evap temp sensors, both in and out. Replace as a pair.
