My husband vacuumed and hosed out our air conditioner and now only the fan works. Could it possibly not be connected right?

when connecting the hose ,there is a possibility that you are pushing the adaptor against the fan if it stops when the hose is removed

Take the front panel off the bottom and check the big hoses that connect to the drum. From what you are saying, the fan is working but not drawing air through the drum. That is why the light is on because it is not sensing air flow through the connections to the drum.

Or Debris in the duct work making it to the fan. Pull all the Hoses that distribute the air and vacuum them out.

the only way to get new fan for a/c outside is to be an a/c tech. not trying to be nosey, but what city state do you live in? i ask because my husband is a/c tech and could possibly save you some money!!!

old system
faulty thermo couple
faulty gas valve
newer system
faulty igniter
leakey vacuum hose / diaphram check by forming vacuum in diaphram connected to first motor that starts up when you turn furnace remote on after you had it off for two minutes

make sure the outside fan is working, if it is then you can disconnect power and clean the coil with a water hose

The AC manifold gauges set have the three chambers: the low pressure chamber (left side), utility chamber (middle), and the high pressure chamber (right side).

When technicians connect the HVAC manifold gauge to the air conditioner units, he connects the low pressure side of air conditioner unit to low pressure gauge side.

If he wants to read the pressure in discharge line he connects the high pressure gauge hose to the air conditioner high pressure side.

The utility port (the middle chamber) is a place you connect the hose to vacuum pump, recovery units or add or remove refrigerant from AC units.

Air conditioning gauges is used to measure air conditioner units pressure within closed-system to evaluate or troubleshoot the AC units. Gauges manifold set is the most frequently used item when it comes to refrigerant or pressure.

Air conditioning gauge set allows the HVAC technician to check AC units operating pressures, transfer AC refrigerant, pressure test system, purge the system with nitrogen, and perform other necessary tasks.

The gauges manifold set includes the hoses, the manifold, the valves, the compound gauge (low pressure gauges) and high pressure gauge.

. Open the gloves compartment (gc) . remove 2 rubber pieces that keep the gc on its place (both sides) . look to the left side. there is a connector with a few thin colored hoses. This thin hoses are there to control the operation of the blend air door. It is vacuum operated. . now follow the thinnest hose, probably it is green, all the way to the right. It connects in a sort of vacuum valve that control the position of the blend air door. make sure it is firmly attached to it. also check that hoses connector to ensure that all thin hoses are well connected. . OK! start the motor and operate the knob on the panel. It should work fine now.

is fan working? if so check the small tube from fan to pressure switch this sometimes will be lose. if fan is working and tube is connected you can check to make sure switch is good by disconnecting hose from fan housing ,start unit **** on hose & hold end so it keeps a vacuum. if everything works than you need to replace fan motor & housing

Yeah, I would go up hill or pull away from a stop and the A/C would cut out and then come back once my speed was stabilized. It was a vacuum hose leak !! This mostly affected the upper dash blower fan.
