Question about Heating & Cooling

1 Answer

We have a York (ceiling mount) air conditioner that has been shutting down 15-30 minutes after it has been turned on. At first, my husband thought it had something to do with a sleeper timer and started working around the "timer". It started working fine. A month ago it started doing the same thing (shutting down after 15-30 minutes) and we haven't been able to fix the problem since. We bought our house with two York units installed and the previuos owner took the owner's instructions with her, therefore, there's no way for us to learn how to even use all the features within the remote control and to be able to find out what might be happening to the Unit. We'd appreciate any guidance, tips or help you might be able to provide. Thanks!!

A. You can write or all a York authorized dealer or The YORK plant itself , theres one one the east coast in Pa, near philly or go internet to find the nearest service place or dealership and ask them f the could send you new manuals . as a certified york representative and former York HVAC installer and member of the pennsylvannia heat pump association. I can say I have not seen many of those old seling jobs their usually in bars combined with smoke eaters and air cleaners ( electric ) so tell mr. fix it to be warry of anything that looks like screens or raxorwie in there or it will blow him right off his ladder if they are activated 220 smoke eaters or aircleaners .

but since the have remotes Id say they probably arent that old. Id get the model and serial #'s of them and try to call a dealership and tell them what you need. it kind of sounds like you have an issue with these "timers' you mentioned. they could be on their way out as in dying... or since somethin like that is usually mounted on a wall instead of on the unit itself so , I may be suspecting they arent timers really at all . if thee are no outdoor condensors for these things it means they are self ontained and probably water cooled or a fan somehow must cool the refriegerant off and blow over the hot condensor .if its just an ac unit or if its a heat pump it would blow cold air over the coil in order to cool off the bloing ot gases in heat mode once the reversing alve opens. I doubt there heat pumps. just staright ac.

now the thing that comes to my mind about these timers. is that usually they woul die after a few weks are you exactly sure they are TIMERS ?? they could be for heat pumps to set them in defrost mode. what Im thinking now this is wthout seing them isthat they are hi and lo limit pressure switches on the ac units themselves and if he turned the limits down and they an better for a while it could be they need to be charged with refridgerant . they way you could tel that is if there are small bras or copper coils or tubes coming out of them connecting to the compressors or to the evaporator coils. which sense the units specific pressure they need to run at top efficency. if he is monkeying around with those limit switches he may already have killed them . but older equipment is fairly durable so I would try and determing the make and model and ask one of the places I mentioned to try to get manuals. Ive mounted an aful lot of sanyo wall mounted units but only a few in celings.

tell you husband to get a flashlite and find those number and write the make and modl of these old yorks , they were very well made back them and could take on hell of a beating , like running them with very little refrgerant in them.

first off is there going to say of we stopped making them and we call sell you new ones for x amonut of $. but Im not a big fan of the new stuff. with puron refrgerant in it.

tell the hubby to look around the compression fiting in which the gas tarvels thru for oil spots which is surely a clearsign up the refridgerant leaking out there. they also have an invetion called a tiff which can search out refridgerant leaks and they can be fied hopefully. dont let them talk yoy nto going into a conversion kit to change them into the new puron gases . if its a matter o a refridgerant loss get some kid who isnt a stickler fo the law and have him put in the refridgeant of the old variety. it should be on the plate, and have him ue that stuff the older refridgerants are better use less electric making cool air . its proebly r-22or r-500 ue them and shhhhushh.... they will out live you. now that only if its a leak othrwisethese controls are usually down where adjst them without taking the celing down.

let me know what you findout. I dont have my pay pal acconut set up yet so this is a tom.m. please excuse my typing and spelling iM tied and must go lie down.

Hampton bay ceiling fan broke. How to screw it back up

It already looks like it's "screwed up". ( LOL) BEFORE BEGINNING READ ALL OF THIS FIRST< PLEASE> First turn off the breaker that supplies power to the fan. Take down the whole unit up to the ceiling mounts. It looks like the wood is broken that the screw bracket used to mount the fan is on. If it is you will need to reinforce the wood and rescrew the fan mounting bracket on it. THe ball carrier from the bracket should now be secure and ready to mount the swing ball of the fan at the top of the fan unit motor. Next rewire the fan to the wires in the ceiling with the wire nuts you removed. Tighten the ball screw and push the cover plate up to the ceiling, fastening it in place with the screws provided to the ceiling plate...Done!

Trying to remove a ceiling fan Hampton Bay model C 542 MP (CH) PBL . its flush mounted and cant get to mounting bracket.

Look for 2 to 3 screws at the top edge of the fan's ceiling cowl. Remove those and the ceiling cowl can be sled down, which will expose the the ceiling mounting bracket . They are fairly small head screws, so look carefully for them.

Hope this helped you and thanks for choosing FixYa.

I want to know the most effecient height as to wall mount my Model LRA257ST2 25,000 BTU air conditioner. Is closer to the ceiling better?

Yes, closer to the ceiling is better. As, hot air rises and cold air falls. Just keep it about a foot off the ceiling.

AC and furnace turn on and off frequently.

Your unit is short cycling. Most likely suspect is the thermostat is mounted in direct line with the discharge air. Adjust diffuser away from stat or relocate stat.

Duo Therm 57915.541

Since you have a knob, I am assuming that this unit has manual controls that are mounted directly below the air conditioner on a ceiling pack. If you smell burned wiring, remove the inside shroud to access the 120VAC connections in the unit. Check these connections for OK, if they look burnt, cut them back and reattach them (be sure to turn the breaker off first). Try the AC again.

If those connections look fine, then remove the upper cover from the unit. Access the capacitors on the side of the unit and check them for ok. If any one of them looks burnt, replace it. These two places are usually the only place that you will get a burned plastic smell.

Hope this helps,

Does anyone know if a Duo Therm model 620515.331c is ducted or not???

The upper unit itself is not ducted. They are all the same. The ducting is done with the lower unit or "Ceiling Pack" of the air conditioner. You need to see your RV is ducted, ie...vents in the ceiling that blow the are out. Usually they are round and mount into the ceiling. Another way to tell is if the unit has a wall mounted thermostat.

Hope this helps,

Furnace won't turn on, off, with or without remote

We hotwired the thermostat wires and the furnace started. That told us that the problem was with the thermostat. We took our remote control to another camper like ours and our remote worked their furnace. That told us that the problem was in the ceiling control for the furnace/ac. But the man who owned the other camper told us that he had a problem, too, and was told to unplug all the electric including the battery, wait 2 minutes, and hook up again. This might reprogram the circuitboard, and voila! It worked.
