*energize

The start relay starts the compressor softly before the main motor windings kick in. The compressor starts when the thermostat tells the compressor it needs more cold in the cabinet.

Fix code P1545 on a 2002 Eldorado


Do you know how to test relay circuit's ? Voltage , control etc...

DTC P1545
Circuit Description
Ignition voltage is supplied directly to the A/C compressor clutch relay. The powertrain control module (PCM) controls the relay by grounding the control circuit through an internal solid state device called a driver. The primary function of the driver is to supply the ground for the component being controlled. Each driver has a fault line which is monitored by the PCM. When the PCM is commanding a component ON, the voltage of the control circuit should be near 0 volts. When the PCM commands the control circuit to a component OFF, the voltage potential of the circuit should be near the battery voltage. If the fault detection circuit senses an unexpected voltage, this DTC will set.
Conditions for Running the DTC
• The engine is running.
• System voltage is between 8-16 volts.
• The PCM driver is activated.
Conditions for Setting the DTC
• The PCM detects an incorrect voltage level on the output circuit that controls the A/C compressor clutch relay.
• The condition exists for at least 10 seconds.
Action Taken When the DTC Sets
• The PCM will not illuminate the Malfunction Indicator Lamp (MIL).
• The PCM stores the failure records.
• The A/C compressor clutch is disabled.
Conditions for Clearing the DTC
• The DTC will clear after 50 fault-free ignition cycles.
• The DTC can be cleared with a scan tool.
Diagnostic Aids
If the condition is not present, refer to Testing for Intermittent Conditions and Poor Connections in Wiring Systems.
Test Description
The numbers below refer to the step numbers on the diagnostic table.
Listen for an audible click when the A/C compressor clutch relay operates. Command both the ON and OFF states. Repeat the commands as necessary.
Tests for voltage at the switch side of the A/C compressor clutch relay. The 10-amp fuse supplies power to the switch side of the A/C compressor clutch relay.
Verifies that the powertrain control module is providing ground to the A/C compressor clutch relay.
Tests if ground is constantly being applied to the A/C compressor clutch relay.
Tests for a short to voltage or for an open.
Perform the calibration procedure for the powertrain control module.

MY COMPRESSOR WONT COME ON BUT THE FAN WILL RUN. UNIT IS NOT SHORTED.CAP. ARE GOOD


If it is an older unit, the compressor may not start (anymore) with the ''correct'' capacitor. (BTW, after checking everything below you should try _new_ caps anyway).

You don't state if it is a window unit or central air. It matters. If it's central air, check the relay inside the air _handler_ (where the fan is). It tells the compressor to turn on and off. The wall thermostat tells the air handler to ''do it's thing'' (so to speak), and the relay inside the handler tells the compressor to turn on. Some older units use what is called a ''sequencer'' (which is just a type of ''timed'' relay switch).

Be careful. There is 220 volts running through it. Make sure _all_ circuit breakers are off. (I mean ''all'' that have anything to do with HVAC in your house, and sometimes there is a breaker outside near the compressor. Make sure it is _off_).

The relays are cheap enough to just go ahead and buy one and replace it. They can go bad after about 5 years depending on usage, humidity levels, etc... It's a good idea to have a spare anyway, so it's not wasteful to replace it as a ''guess''.

If you're certain of _all_ other parts, then you can try a compressor capacitor ''booster.'' They give extra life to compressors that cannot start with just the correct cap anymore. However, be aware that such a situation is highly energy inefficient. Such a compressor would be eating excess energy just to run itself.

Note however, if the ''start'' winding in the compressor is bad, the booster will not work.

Sometimes the ''run'' winding is bad. If so, the compressor will try to start and then fail. (i.e. it won't just sit there dead doing nothing). If that's the case, you _could_ rewire it to actually start _and_ run on only the start winding. However, it will be extremely energy inefficient and will only last a couple of months (at most). You can find info on how to do such things on the web.

It's not particularly dangerous (once it set up that way), but is _is_ the definition of ''jury rig'' and I would be remiss to not caution you against doing it. I only mention it because I know what it's like to not have AC and also not being able to afford an entire replacement system.

Do not attempt _any_ of the above unless you really understand what you are doing. Unfortunately, you _will not_ find a professional willing to do such a thing for you. I even doubt you could find a pro willing to install a start booster.

Ps... Hopefully it is just a bad relay. However, if it is not a relay, and if the cap ''booster'' thing works, you can leave it that way until it fails. It may even last for a few years. Just be aware your energy bills will be about 1/3rd higher.

In closing, the ''start winding'' solution is an extreme ''jury rig'' and it _will_ fail (the winding will burn out) within days to months; there is no way to tell how long. So, if you do go _that_ route, understand that it is _very_ temporary.

Freezer in defrost to long


The motherboard determines the defrost time and how often, but I don't think it is the most likely reason for what appears to be a extended defrost. Sometimes the start relay, overload and run capacitor fail causing the compressor to short cycle. Sometimes the whole problem is caused by a defective condenser fan motor that stops and runs or runs poorly causing the compressor to overheat.
Here are the parts=> WR62X0079 Run Capacitor
WR08X10025 Overload
and the WR07X10084 Start Relay

The condenser fan is=> WR60X10220 Condenser Fan Motor

If the AC compressor is kicking in and out then you are probably low on freon. If the Compressor isn't kicking in at all then the problem could be a fuse or relay in the Power distribution box or the fuse in the interior of the car. If the fuse and relays are good then the problem could be a bad clutch on the compressor or a bad compressor itself. If the compressor is kicking in and out then get a freon refill can from Walmart or an Auto parts store and add freon to the system until the compressor kicks in continuously.

Air condition don´t start, a honda civic


Air conditioning systems sometimes leak down and won't turn on when the refrigerant levels are too low.

Lift the hood and listen to the A/C compressor while someone inside the car turns it on.

Does the compressor engage for a second or two and then shut off?
If it does....you need to have your system checked for leaks and recharged.

If the compressor never comes on. Look at the A/C compressor relay. It should be under the hood in a little fuse box with other relays and fuses. When you find this relay you need to see if it works. You can buy a replacement relay and swap it or take it to a parts store and have it checked. Relays are 10-30 dollars and you should have three or four relays of the same type so a real cheap test is to swap a identical relay from an electric window or a defroster. You should see them sitting right next to the A/C relay if you have them.

Good luck and be careful!

1. GE is replacing many defective boards free of charge. Check with them to see if you are qualified.
2.The start relay should be closed when refrigerator is de-energized.
3. Still a possible bad compressor or compressor start components. Test performed by service tech on compressor is usually done with a starting test cord. Would answer many questions quickly.

The unit is a 12000 BTU energy efficient model purchased from Lowes 3 years ago. It is not cooling. The fan runs fine but it just isn't cooling. The filter doesn't need cleaning. What could it be?...


The compressor is probably not running.

The Main reasons that this will happen
1 - A bad run capacitor (silver or metal capacitor)
It’s either shorted, grounded or open.
If it’s shorted a lot of times it will bulge out, (sometimes slightly)
2 - A bad start kit ( plastic capacitor and Relay connected to it )
The capacitor is either shorted or open
The relay either has an open coil between terminals #1 and #5
Or the relay is stuck.
Any time you change the capacitor or relay you should change
the other, especially if they are over a year old.
3 - A loose, burnt or disconnected wire
4 - Wired wrong
5 Compressor is open (windings burnt open)
6 Low on charge not getting enough cooling back to compressor, (Feel top of compressor to see if it’s hot it shouldn‘t be)
7 Some compressors have a black plastic overload under the compressor cap which could be bad.

A/C compressor works intermittently


Hello< will try and help you.Try replacing the low pressure switch,and the high side compressor cut out switch,look on the low side for the low pressure switch(large line/hose).It will have to wires gong to it.The high side cut out switch will be on the high side line/hose,or in the back of compressor.If this doesn`t help Have the system pressures checked.If I can help anymore...roniecon@gmail.com
