What causes an Econar GeoSource 2000 to ice over?
- N
  Nancy MorrisonAug 26, 2025
  If your Econar Heat Pump's evaporator (air coil) is icing over, it could be due to: * Dirty air filter: Inspect the filter and clean or replace it if it's dirty. * Airflow issues: Ensure adequate airflow and proper air distribution. Check the motor speed and duct sizing. Check the filter, it should be inspected every month and changed if dirty. Also, check for closed registers. Remove or add resistance as needed. * Evaporator blower motor tripping: Check for an overheated evaporator blower motor and a tripped overload. Replace the motor if necessary. * Low room temperature: If the room temperature drops below 65 degrees, the evaporator may ice over.

What causes an Econar Heat Pump to short cycle?
- B
  Brenda GibsonAug 31, 2025
  An Econar Heat Pump might short cycle due to: * Thermostat issues: The differential might be set too close on the thermostat. Readjust the heat anticipator to 1.0 or 1.2. * Thermostat location: The thermostat might be improperly located (e.g., near the kitchen), inaccurately sensing the comfort level in the living area. * Wiring and controls: Look for loose wiring connections or a defective control contactor. * Compressor overload: A defective compressor overload could be the issue. Check and replace if necessary. If the compressor runs too hot, it may be due to an insufficient refrigerant charge.

What to do if my Econar GeoSource 2000 Heat Pump won't operate on heating?
- K
  Kelsey CrawfordSep 3, 2025
  If your Econar Heat Pump isn't operating on the "heating" setting, check the following: * Dirty filter: Check the filter and clean or replace it if it's dirty. * Thermostat setting: Ensure the thermostat is set to the correct temperature. * Defective thermostat: Check the thermostat operation and replace it if found defective. * Incorrect wiring: Check for broken, loose, or incorrect wires. * Blower motor: Check the blower motor in one of the other switch positions. If it doesn't operate, check for an open overload. If the overload is open and the motor is not overheated, replace it.

How to troubleshoot water drips from my Econar GeoSource 2000 Heat Pump?
- C
  catherine57Sep 6, 2025
  If water is dripping from your Econar Heat Pump, consider these potential causes: * Unit not level: Ensure vertical units are level. For horizontal units, level those using a bottom condensate drain and pitch those using a side condensate drain. * Clogged drain line: Clean the condensate drain line to remove any kinks or plugs.

How to fix noisy operation (continued) in my Econar Heat Pump?
- J
  John ReeseSep 9, 2025
  To further address noisy operation in your Econar Heat Pump: * Rattles and vibrations: Check for loose screws, panels, or internal components. Tighten and secure them. Also, copper piping could be hitting metal surfaces; carefully readjust by bending slightly. * Water and airborne noises: Undersized ductwork can cause high airflow velocities and noisy operation. Excessive water through the water-cooled heat exchanger can cause a squealing sound. Check the water flow to ensure adequate flow for good operation while eliminating the noise.

What causes my Econar Heat Pump to heat only and not cool?
- K
  Kylie ReyesSep 12, 2025
  If your Econar Heat Pump only heats and doesn't cool, it could be due to: * Reversing valve not shifting: A defective solenoid valve may not be energizing. Replace the solenoid coil. * Stuck reversing valve: The solenoid valve may be de-energized due to miswiring at the unit or thermostat. Correct the wiring. If the valve is tight or frozen, and won't move, replace it. Try switching from heating to cooling a few times to loosen the valve.

Why is my Econar GeoSource 2000 Heat Pump unit not running?
- E
  Edward SmithNov 16, 2025
  Your Econar Heat Pump might not be running due to several reasons: * A blown fuse or tripped circuit breaker: Replace the fuse or reset the circuit breaker, ensuring it's the correct size. * A blown fuse on the controller: Replace the fuse on the controller, again checking for the correct size. * Broken or loose wires: Replace or tighten any broken or loose wires. * Low voltage supply: If the voltage is below the minimum specified on the data plate, contact your local power company. * Low voltage circuit: Check the 24-volt transformer for burnout or voltage less than 18 volts. * Thermostat issues: Test the thermostat by setting it to "Cool" at the lowest temperature and then to "Heat" at the highest temperature. If the unit doesn't run in either case, the thermostat may be fau...

What to do if my Econar GeoSource 2000 has insufficient cooling or heating?
- S
  Scott Huang Jr.Nov 18, 2025
  If your Econar Heat Pump isn't providing enough cooling or heating, consider the following: * Water issues: Ensure sufficient water pressure, temperature, and quantity. * Undersized unit: Recalculate heat gains or losses for the space. If excessive, improve insulation or shading. * Air leaks: Check for leaks in ductwork or ambient air entering through doors and windows. Also, ensure the thermostat isn't near a kitchen or other area that could cause inaccurate readings. * Airflow problems: Verify adequate airflow and proper distribution. Check motor speed, duct sizing, and filter condition. Clean or replace the filter if dirty. * Refrigerant charge: A low refrigerant charge can cause inefficient operation. Adjust the charge only after checking CFM and GPM. * Compressor issues: ...

Why is my Econar Heat Pump blower motor running but the compressor isn't?
- M
  Michelle BallNov 21, 2025
  If the blower motor runs but the compressor doesn't (or short cycles) on your Econar Heat Pump, here's what might be happening: * Thermostat: Check the thermostat settings, calibration, and wiring. If your thermostat has an anticipator, set it to 1.0 or 1.2. * Wiring issues: Look for loose or broken wires at the compressor, capacitor, or contactor. * Blown fuse: Replace any blown fuses or reset circuit breakers, ensuring you use the correct size. * High or low pressure controls: The unit might be off due to a high or low pressure cutout. Check water GPM, air CFM, the filter, ambient temperature, and for any loss of refrigerant. If it still doesn't run, check the pressure controls individually and replace if faulty. * Defective capacitor: Inspect the capacitor and replace it if d...

How to fix noisy operation in Econar GeoSource 2000?
- B
  Brian LoweNov 27, 2025
  To address noisy operation in your Econar Heat Pump, consider the following: * Compressor: Ensure the compressor isn't in direct contact with the base or sides of the cabinet. Cold surroundings can cause liquid slugging, so try to increase the ambient temperature. * Blower and blower motor: Check if the blower wheel is hitting the casing and adjust for clearance and alignment. Inspect the blower for bends and replace if damaged. Tighten any loose blower wheels on the shaft. Check for defective bearings and replace them if necessary. * Contactors: A clattering or humming noise in the contactor could be due to a control voltage less than 18 volts. Check for low supply voltage, low transformer output, or extra-long thermostat wire runs. If the contacts are pitted or corroded, or the co...
