What the Best Split level AC Units...Carrier LG, Panasonic?

[DMan7]

Is the board inside the evaporator or inside the A/C unit?

[Jerry84]

To answer both persons the relay is stuck on evaporator. You need a new evaporator board or get a new relay soldered onto the existing board.

I was thinking that if the relay is stuck wouldn't the unit be constantly running? My unit is cutting off and coming back on at short intervals, just not reaching the desired temperature before cutting off, hence short cycling.

But I could be wrong.

That answer wasn’t for you Jerry. The other Two guys. Your issue is likely with the evaporator fan when you see the big line icing up it’s not moving enough cold air as it should.

Crack the evap a hard slap on the right hand side of you facing it.

Suction line is icing because refrigerant has not changed phase from liquid to gas in the evap. This is from low heat load, be it clogged filters, coils, dirty blower wheel etc.
As the liquid refrigerant enters the suction line and there is space to expand it takes heat from the air surrounding it and condensed humidity forms ice on the line.

So essentially the unit needs a proper washing out and servicing.

AC tech came and did exactly that yes, started working as it should, but he says it will happen again.

Might just change the unit, it's over 12 years old by now.

Sorry for the later response. Unit was thoroughly cleaned and this continued to occur. Temperature in room is not building to the value set. I believe it's safe to rule out dirty unit etc.

So further to my observation before where I've noticed that my ac unit was short cycling, I've also now noticed an issue which could be a contributing factor. When the compressor cuts off, the fan speed apparently slows down to the point where it sounds like it's almost off. Then after some seconds it speeds back up. The fan is almost non functional at speeds 1 and 2 where you bearly hear or feel the breeze coming out. Also the "turbo" feature is equal to speed 3 of the fan and not more.

Therefore the common issue surrounding the observation is the fan speed. Could this be the cause or associated with the cause of the short cycling?

Is this a separate issue all together?

That’s why my reply to you earlier was that the evaporator fan motor is the issue. It can be the fan capacitor on the board or the fan motor itself

[DMan7]

Yea fellas, even though the hitting of the side of the A/C unsticks the relay switch and turns off the condenser outside, it starting to require more hitting of the A/C to turn it off, sometimes I feel like I does wake up my neighbors with the noise of the hitting of the side of the A/C all the time. lol That switch will obviously have to change.

What's the solution to this? Is it that the board itself has to change? Or the fan capacitor is easy to change?

[jehusaunders]

Unless you skilled at soldering, then changing the board is the only solution. Listen for any abnormal noises which will indicate that the fan motor is failing. If not its the fan capacitor.

[pugboy]

it is possible the cap bad and hitting the unit a lash jerk the blades to spin and keep going

caps are easy to change

[nervewrecker]

Sounds like a voltage issue. Loose or corroded main connection.

Where can I get the circuit board for a GE r410a unit and the estimated cost? Size is 12,000 BTU

[Jerry84]

This is the sticker on the unit with the specifications.

[nervewrecker]

Continental. Have a branch in couva and princess town. Use google maps

Can anyone provide feedback on Coleman units?

[jason_79]

Anybody?

[nervewrecker]

Midea built, same as intense cool, comfee etc

[jehusaunders]

Can anyone provide feedback on Coleman units?

They coming with a 7 year warranty which I think is the most on the market for Chinese units.

[Jerry84]

Curious to know what's the recommended reading via the guage set you technicians use to determine the correct psi for a 12000 btu unit that uses r410a gas?

I usually check the compressor running amperage and charge accordingly. It usually lands up around 125ish

So would a reading of 112ish be too low as to cause the thicker line to ice up?

Clean your evaporator and condenser proper first I’d say then check

This was done already. I'm only assuming that the unit needs a top up of gas as it's been in use for about 4 years.

What could cause a split unit to turn on by itself, took the batteries out the remote, but it still happens randomly.

There is supposed to be a button/microswitch inside the evaporator of unit to turn on. Lift the evaporator cover which grants access to change filters and look around for it. Could be it shorting closed intermittently.

[Jerry84]

What's your thoughts on the Infinity Inverter units that seem to be flooding the market?

I saw a company advertising a 12k inverter for $3200 installed.
