Below are photos of a ?fuse? that is clipped to the block just in front of the coolant filter on my 7010. I must have bumped it when replacing the filter recently. What is this? The wire runs up to the air conditioning compressor. What do I look for when trying to find a new one? Thanks, Roscoe  |

| It's a GM air conditioning fuse or sometimes called a thermal limiter. Any automotive parts store should have that. |

i think that's whats left of the thermal limiter fuse for the air conditioning system! ------------- 1-B's, 2-C, 2-CA's,2-WF, 1-WC,1-G, 3-WD's, 2-WD45, 1-RC, 1-D17 Diesel, 1-D14, 2-D15,1-D17 row crop,1-D19 gas and All Crop 40,60,66,72,90 and 100 |

| Just ask for a GM air conditioner fuse or take it off and bypass it. MACK |

| I agree with the bypassing |

So just stick a jumper wire in the two outside slots? Thanks! What is a thermal limiter supposed to do, anyway? |

Stolen from the internet, cause I am too lazy to type....... A thermal limiter is much like a fuse. This device was used on many General Motors cars and trucks during the mid to late 1970s and was designed to help protect the compressor inside the air conditioner. The thermal limiter switch keeps the clutch in the air conditioner from engaging when the air conditioning system is low in refrigerant. The superheat switch sends the information to the thermal limiter switch to prevent the clutch from engaging. When refrigerant levels in the air conditioning system are too low, the evaporator within the system will be forced into superheat conditions. This simply means that the vapor from the refrigerant in the system’s evaporator will become overheated. When the superheat switch, which is located in the rear head of the air conditioner’s compressor, gets the signal that the evaporator is being overheated, it will send the message to the thermal limiter switch which will in turn completely shut down the air conditioning system within the vehicle. This is done to prevent damage or failure of the system. ------------- Still in use: HD7 WC C CA WD 2-WD45 WD45LP WD45D D14 3-D17 D17LP 2-D19D D19LP 190XTD 190XTLP 720 D21 220 7020 7030 7040 7045 3-7060 Projects: 3-U UC 2-G 2-B 2-C CA 7-WC RC WDLP WF D14 D21 210 7045 N7 |

a words of caution - if the coil on the compressor clutch is drawing too many amps it will blow the fuse,,, by passing it will eventually melt the harness..// check the amp draw on the coil - should not be over 5-6 amps. country boy way to check is take a 12v powered wire and touch it to the coil wire with a 5 amp fuse in-between - should not blow fuse.
