How to fix Whynter ARC-126MDB that does not turn on?
- BBethany HancockAug 6, 2025
If your Whynter Air Conditioner doesn't turn on, check the following: * Ensure there isn't a power failure or outage. * Check if the automatic switch, line fuse, or breaker has been tripped and restore it. Too many appliances on one circuit can cause this, so move some to another circuit. * Verify the power supply voltage is correct and move the unit to a suitable circuit if it's too low. * Inspect the power cord for damage. If damaged, call for service; only authorized personnel should replace it. * Check the L.C.D.I. power plug and press the Reset button. * Drain the water if the internal reservoir is full and ‘P1’ appears on the display. * If none of these solutions work, there may be a loose internal connection; contact Whynter for service.
