Subject 1 of 2 Trane Air Handlers 4tgb... I have dual

Subject 1 of 2 Trane Air Handlers 4tgb... I have dual systems here at the house both systems are down.. Taking one at a time...JA: I'll do all I can to help. How long have you been dealing with this?Customer: This system a few days... the other system I had my HVAC guy on it and his daughter died before he could trace the short in the 24 volts... Both systems at different times had melted one leg of the 60 amp breakers.. That is repaired... Please note that I am an electronic and former senior service engineer for Afga and NASA with little or no experience in HVAC but I can troubleshoot and follow schematics. Here is what I have right now.. After replacing the thermostat, it was acting flaky, now seems to work consistently, everything appears to work... Oh and by the way these have electric coils as aux heat... The relay to the coil is now engaging properly and there is proper voltage to the coils...and the coils measure around 11 ohms with power off so they must be good. I also think they must be good because with fan only my clamp meter indicates .5 amp at the air handler breaker input, but when the thermostat is demanding aux.... the amperage increases to about 10 amps on each leg... But it is still cold as hell and won't go past 57 degrees. This may have been going on for awhile because I noticed the aux stays on for a long time, but in the last few days the outside temp dropped below 20 degrees and the heat exchanger can't keep up with that... so the question is why am I drawing amps because of the coil but they aren't producing heat????JA: Did you double-check the thermostat's settings? And what about the filters?Customer: The hvac dude programmed the thermostat that I borrowed from the other system that was down... what is there to check? the relay to the coils is engaging but no heat, as though there was an open coil, but can't be because of resistance and amp readingsJA: Do you plan on doing the work yourself?Customer: i am tryingJA: Anything else we should know to help you best?Customer: for this side of house no

I have a cold draft coming from my main return vent. I

I have a cold draft coming from my main return vent. I opened up the vent grill and made sure there were no holes, cracks etc. I took pictures and sent them to an HVAC contractor for advice. They were sure I needed to use foam sealant even though there is no evidence of air leakage. I did some sealing and nothing changed. I read that I might need a back-draft damper?Note that my system is outside and I have no option of bringing it inside. If cold air is dropping to my vent because of the outside duct work, will the back-draft damper reduce the flow of the cold air to my inside?

I purchased a Goodman GDH80804BX 80,000 BTU 80% AFUE no nox

I purchased a Goodman GDH80804BX 80,000 BTU 80% AFUE no nox down-flow gas furnace.I followed the installation instructions that came with the furnace. I wired the units thermostat leads as Red to RH / White to W=heat and Blue to B+common, hooked up the power and installed an ON - Off Power switch in the furnace closet. My A/C unit is a Bard, self contained unit outside and the cold air is blown in by 2 12" flexible double insulatedducts, The A/C and Heat both use the same duct work and the same thermostat. I should have mentioned its a mobile home install. When I set the thermostat, turn the thermostatswitch to heat and turn on the power (Nothing), But a six flash error code on the circuitboard. The 6 flash code says to wait one hour so the unit can reset and try again. HELP!

I have an error code that says to manualy reset the rollout

Hi, I have an error code that says to manualy reset the rollout switch. I think I have found the switch but not sure how to reset. The furnace manual implies that it can be reset and not to install a new one...Thanks!!JA: How old is the appliance? Have you gotten error messages before?Customer: It is only a few years old. High efficiency condensing furnace. I am sure the problem was caused while insulating the attic and some leeds to the thermostat were grounded, so I understand why you are asking. I think the furnace is fine. Never had error codes before..JA: Do you plan on doing the work yourself?Customer: I am hoping to as it is a holiday. I am an engineer and machinist so I am used to doing some work, I usually don't break things. Not always.JA: Anything else we should know to help you best?Customer: Not that i know of Just checking, What is the total cost for this help?

View more insulation questions
Questions you might consider asking
  • When my a.c. was recently replaced they did not put insulation on the outside lines, is that required? Also, they broke a door frame trim on the inside a.c. closet; is it unfair for me to ask them to fix it?
  • Why does the unit discharge fibers as though there is insulation inside the unit? We have a fuzz all the time and we worry about our lungs.
  • Does the building code in new jersey require R-8 insulation on heating ducts in a single family dwelling?
