SOURCE: Error code of E4 on Dometic HP air conditioner ??

16. SYSTEM RESET
a. Turn the ON/OFF switch to “OFF” position.
b. Simultaneously depress and hold the MODE and ZONE
push-buttons while turning the ON/OFF switch to “ON”.
FF should appear in the LCD display until the MODE
and ZONE push-buttons are released.
c. When a dip switch is turned on or off after initial configu
ration, a system reset will need to be done before the
Comfort Control CenterTM will recognize the updated selection. Try this. This is for the five button thermostat. Did you check the dip switches to be sure the proper ones are turned on? I need to know which stat you have 4 or 5 button. I have trouble shooting for both.
If you notice reset needs to take place after a dip switch is turned on or off. The dip switches are on the circuit board. You need to drop the lower cover. the dip switches will read in this order #1 heat strip/ #2 zone2/#3zone3/ #4 zone4/#5 furnace/#6 differential/#7stag/#8 gen start. Check this out and be careful. Turn off the stat to change dip switches. On will be toward the description. If you don't have remote start gen set the dip should not be on. If you dont have a Zone 3 the dip should not be on, etc.
Any questions feel free to post back
Thank you for using fixya

Portable Air Conditioning great portable air cooling


Portable air conditioning offers you the convenience of mobility. All you have to do is roll the portable air conditioner to the room in which it's needed. Install an exhaust hose out a window or other opening (everything you need is provided) and turn it on. The installation process for these units is very simple. These portable air conditioning units are built small enough to be very mobile and are supplied with wheels for easy movement. A portable air conditioner will also work very well in apartment situations where you will often find a window unit is unacceptable.

Portable air conditioners are very unique in that they are portable and can be easily moved to different locations in your home or business. They can be a highly effective way to either help out an existing HVAC system in one room or cool a single room entirely. They are also one of the best ways to cool a room or area without having to install a window mounted unit.

These air conditioners use a compressor and Freon to cool just like normal air conditioning. They are very effective in cooling rooms and to keep the humidity low. Like normal air conditioners portable units extract hot air that must be vented. That is why they need to have the exhaust hose to the outside. These units can cool air as well as air conditioning done with window air conditioners. However they do not require installation like conventional window air conditioners this makes them very convenient for seniors or physically challenged people. Most portable air conditioners are supplied with a window kit. This kit contains exhaust hoses that will work in any window: double-hung, casement, awning or slider. Because they vent through an opening like a window they require no permanent mounting like window air conditioning.

Portable air conditioners are a very good cooling option for those who can't use the more conventional air conditioning methods. Remember though that this type of unit is not as efficient as most window units or conventional air. So while they may make your environment cooler, it won’t turn your tent into a room at the local hotel.

So as you can see these air conditioning units have some great advantages over other types of air conditioning. They are a great alternative for unique applications where central air or conventional window units are either unfeasible or too expensive. During special events, portable air conditioning can also be a great way to keep guests or equipment cool and comfortable. Always be aware though that because portable air conditioning will remove moisture from the air, they will also need to be drained occasionally similar to a dehumidifier.

Does your application warrant a permanent air conditioner of some form or should you just use a portable one? There are some interesting things to consider when making that choice. Weigh out all of the different options and make that decision based on what will best suit your needs.

Sounds like an interconnecting wiring error. Check wiring connection i.e. wires are connected in right order 1 to1 2 to 2 etc. from indoor terminal board to outdoor terminal board. Also check for slack or loose connections.

I have got a problem with an lg inverter its a 24000btu/hr,the indoor is flashing six times and the outdoor unit is off,what can l do to make this unit run again?


Inverter compressor run current high. Check compressor windings all equal 1 to 4 Ohms, Check to earth 50 MOhm minimum, check run current. If it's high, or windings open circuit, replace compressor.

What is the power draw (in watts or amps) of the Kenmore 5300BTU room air conditioner? The unit is being powered off the grid by an inverter, and I think the user chose too light weight an inverter for the...


5.8 amps. see page 9 (5300 btu is considered a 6000 BTU, 4800 is considered 5000 btu, sorta like a 2x4 ain't really a 2x4 LOL)
You cannot run an ac on an inverter, not enough juice to get it started.
