Is that a 16 degree diferential? If so, that might be normal if you are in a high temperature, high humidity area. Could be all it can do. But you can check to see if the filter is dirty or if the unit is dirty. Both the indoor and the outdoor coils need to be clean. If you still have a problem and the unit is not dirty, then it may be a little low on refrigerant.

Comfort zone cz2011 heater shuts off


I had a similar issue. It would cut off after approx 30 sec to 1 min. If the power shuts off or screen and lights go off most likely the problem is the thermal cutoff switch comonly called a thermostat. (Be Sure you are getting good air flow also check filter JIC) I found the problem but the parts in the systema are cheap off brand parts. Low quality circuit boards and soldering. The PN on the switch was unknown. Since I didnt know the cutoff temp I called the mfg which did not offer any parts, prints etc. This is an expensive throw away heater is basically the answer I recieved. My unit also had very low use as it is used as a supplimental heat ocassionally. Instead of tossing the unit I looked a little closer at the switch. I found 120 deg C stamped on one of the .25 QC terminals. On the front it is stamped 120/240V 16A. After a search I found the SRL250. It is a 250 deg F 15A 120/240VAC. (120 deg C = 248 deg F). It is 1 amp less which is fine as the 1500W unit should not draw 15 or 16 Amp. I now have the heater running again. You can find this part online or you local appliance parts house should have it. Or Cross ref to another mfg. Hope this helps.
Orig- 120/240VAC 16A 120 deg C (Open on Rise)

Unit will not heat, change batteries controller cleaned filters etc. Still blowing COLD air


Check the thermostat setting...in the auto machines, with a reversing valve, there is no heating or cooling, generally, in the sensing temperature band of 19 Deg C to 22 Deg C and it only works on blower mode, re-circulating the room air. When the sensing temperature goes below 17 deg C, it works on heating and when the sensing temperature goes above 24 deg C, it works on cooling

I have 2 Coleman roof ac's on my 34' coach that are ducted. The fans work and the compressors come on but the air isn't cold enough to cool the coach. The front unit temp only goes to 70 deg....


Are there any filters? If they are clogged the unit will not work properly and the temp will not drop as much as it should as it cannot absorb the air in the trailer or room.

Split system getting cold at first then just not cooling the room


Split Air Conditioners are not meant to run constantly. so check this first . you may have a faulty component i.e. compressor, condenser, evaporator, or evap fan. Depending on your technician you may have gotten ripped off. You need to find out if he checked the system for refrigerant (gas) leaks. A good way to tell if your ac is leaking is feel the low and high side copper pipe in between the inside and outside units.
the smaller pipe (high side) should be hot be carefull maybe touch it with an ice cube. The Large pipe should be cold but not iced over.
if there is ice on any component you should call a qualified tech. you probably have a leak. you should also clean your air filters which are right above the vents. I am a certified AC mechanic and i have seen this problem. in Iraq because of ambient temperatures being high the systems take alot of abuse and we dont fix them because repair costs exceed replacement costs alot of the time. good luck.

Have WeatherKing Model 10 aja 1801 s/n 6827 m2602 04732


I would say that you are Right.... Sounds like that is it. It's only cooling good lower temp. because it is lower temp. check the temp. of the air coming out. should be about 48 to 55 % anywhere in there is where it should be. But keep in mind the cooler the house the cooler the air will get coming out..

The fan on my central heating system keeps running


IN MOST PROGRAMMABLE STATS THERE IS A FACTORY DEFAULT PROGRAM.IT COULD BE
RUNNING IN THAT MODE.FIRST,CHANGE THE BATTERIES IN THE STAT.ALSO,THEY HAVE A
RESET BUTTON ON THE CIRCUIT BOARD.TRY THAT.AND,BY THE WAY,YOU ARE NOT SAVING
ANY MONEY BY DOING A TEMP SETBACK.THE HEAT SYSTEM WILL USE JUST AS MUCH
FUEL EVERYDAY TO RECOVER THE LOST HEAT DURING THE SETBACK PERIOD.ALSO,THE STAT COULD JUST BE BAD.
