Actually - it turns out to not be a big deal. Turning power off to the HVAC system and then back on again powers the interface turning on a timed wi-fi signal. I can connect to this signal (network)...
Yes, the interface is installed and running (solid red LED). No wi-fi signal.
My OEM GE Gentec ECM variable speed blower motor failed. When it was working, the motor would spin up gradually, run until temperature set point is reached and then continue to run for 90 seconds...
I bet it's the module as well. Whenever I had "motor" failures, it is the bearings and bushes leading to the motor freezing up and/or not turning easily. This motor spins freely with no noises...
It's 13 years old (installed 2010). It's in pristine condition simply because I maintain it. The filters are high quality and it never runs without filtration.
When I opened the access to see if the...
Thanks for your reply.
It is a 16 pin true VS motor. Years ago during a thunderstorm while the AC was running, the thermistor in the ECM control module fried. It was easy to replace and the fan...
I have a Trane 1 HP variable speed air handler motor which has failed. It has two parts, the ECM control module and the DC motor itself.
MOT09233 D341314P05 (ECM 2.3). When power is supplied and air...
What is the difference between a start relay part label shows: RVAH21AEKL 197U840 (D154983P01)
and the same part but with 197U550 showing? Both are 40A-400VAC. Jut curious what the middle part...
Not DIY - just looking at the configuration for when the HVAC repair guy comes out. I build electronics (hobby) - no worries on that front. It's more of a desire to understand the design and what...
I have a trane XR-13 model which has a GE 97F9899 35 MFD 5 MFD capacitor
This cap had 3 terminals on top. I am curious what this cap controls? What does it do?
There is a compressor start cap as...
Thanks!
Let me rephrase -
When HVAC professionals replace start capacitors at the compressor which has both a start capacitor and a separate run capacitor, is it customary to replace both at the same...
The start relay is fine. Once I replaced the start capacitor with a new one, the unit started up and runs as before. My question is whether the currently working run capacitor should be replaced at...
The start capacitor for my 2-stage 10 year old Trane system failed. It was simple to replace, and the compressor is back up and running, but I wonder if I should replace the run capacitor as well?...
Success!
I was able to get the ice maker to start up again. Absolutely nothing wrong with the unit - strange, however what it was.
Apparently, shutting off the circuit breaker does not...
I poured warm water over the bin thermostat until the drain pump turned on. I ran a hair dryer under the unit into the compressor/condenser area to see if I can trigger a start.
No luck getting the...
Clean cycle never starts.
All of the buttons work in the sense they light up when pressed, but nothing happens. If I hold the power button down (to start), the blue "ice" indicator will flash 3...
What is I O M ?
I'll try that (clean cycle).
No success. It's been hours and the machine will not start.
Something tripped and is not resetting. As the machine is only six months old and was working flawlessly, I can't imagine catastrophic...
Thanks for this! I will see if it re-starts on its own. The way it stopped was puzzling. Maybe adding too much water to the storage bin (cleaning) triggered a fault (drain pump not draining fast...
I have a new six month old SM50 unit which worked perfectly. I shut down the unit for winterizing (Houston freeze) and stored the unit in a heated garage.
After re-connecting, the unit came on and...
Absolutely on the jumper - it was just a test to see if the unit starts and runs given that it had plenty of pressure when it was off. Once it started and cold air was flowing, I let it run for 10-15...
I reset the board. I bypassed the low pressure switch and the unit started up. Low pressure 118 High pressure 400 r410a. 80 degrees outside. Inside set to 74.
Air return was nice and cold with a...
Yes ... but in your experience, have you replaced many low pressure switches? Is this a common failure?
I have a 10 year old Trane dual stage system. The compressor control board is throwing a fault code indicating low pressure cut out - 7 blinking red LED. This happened last season and all I had to do...
I have a 315I sub-zero ice maker which is made by Scotsman - parts are the same.
The drain pump started to run continuously when normally it cycles on and off as the ice melts and water...
The red led blinking 7 times in rapid succession is for sure. It is the only fault that "lights" up when the unit cuts out. It is 'intermittent' in the sense that I can go weeks with no issue then...
I live in Houston - a major AC city! And I was just told it will take 3 -4 days to get this part in from Trane.
Contractor showed up and confirmed my suspicions. Low pressure cutout sensor is not working properly. When the unit called for cooling (all dampers opened - max cooling), the compressor came on and...
Temperature at night was about 75 outdoors. Indoors temperature was rising to 80 degrees. Thermostat is set at 74.
I checked refrigerant pressure with a gauge and it was around 150 psi. Since I...
I have a 9 year old two stage Trane system. During the night the compressor stopped and gave a "low pressure cut-off" fault code (red led blinks 7 times).
The pressure is fine - so I suspect a...
Will this one also work:
RTH8580WF
I can buy it today rather than wait for the other one to be ordered.
Thanks
My TH8321U1006 two cool stage/ three heat stage Honeywell thermostat is no longer working after 8 years of service.
I'd like to replace it with a Honeywell wifi unit.
Would someone recommend as...
What is it the installing contractor does that can cause this unit to fail like this?
Nothing but trouble from these units (all five of them that I own). Every single expansion valve and evaporator...
Well....so far the AC has been working all week since the compressor lockout over the weekend.
Inside air temp is set to 74 overnight. Outside air temp in Houston is in the 80's now. This is not an...
I have a Trane two stage 5 ton AC system (installed 2010)
A few days ago, the outside condenser/compressor unit was off and the inside blower was running (blowing warm air).
I checked the...
My Vision Pro TH8321 thermostat backlight no longer works when I touch the screen. Strange, when I unplug it from the wall (on battery power at that point), the backlight will come on when I touch...
Thank you.
I suspect the Evaporator coil ... I have had to replace everyone of them on my other AC's (we have 5). This is the last one. I suspect it is rusted out like the others were. Six years...
I have a Trane XL16i two stage AC system. The outdoor unit has stopped working.
The control board has a red fault LED which is flashing 7 times.
Can someone tell me what 7 flashes indicates?
...
I recently had a Honeywell zone damper "fail". The failure was caused by sticking and the repair technician restored operation by simply operating the damper by hand to 'free' it up. The motor then...
There was no code - just a blinking red light under which it is labeled "fault".
Service technician was called earlier - but I don't expect a response from them until Monday. I was more curious what is "likely" based on your experience with these things. I'm technical and...
My Trane two stage condenser, model # 4ttx6060c1000aa, stopped running overnight.
When I checked the control board, a fault light was blinking. I unplugged the board to reset it - plugged it back in...
It figures - right?! A $2,000 unit and when I need it most. 7-11 won't work because they don't sell the perfectly clear cube ice for Scotch (otherwise I would just use the refrigerator's ice maker)....
I own a Sub-zero Ice maker that is a re-branded DCE33 Scotsman.
It is two years old and under warranty - but of course - it has stopped making ice during Thanksgiving
(just like heaters going out...
My old house had 3-phase (Ruud) and Facilities Mechanical (commercial) did the maintenance work. I have asked them to look into doing this job for me, but my contractor has his own guy (who he likes...
Thanks for the update - I will look into the variable units! Seems like a smarter way to go.
I am building a new home (10,000 sq. ft. AC space). The old home I tore down had 3-phase power to the older AC's. My contractor wants to replace them with single phase AC's believing them to be...
