Recently, a homeowner in Downers Grove, IL called us after their Frigidaire gas range (Model: FPGH3077RFE) started acting up. Everything seemed normal—until they preheated the oven.

Then, the dreaded F50 error code flashed on the screen.

 The Problem: A Great Range That Suddenly Stops Working

The F50 error usually appears right after preheating, when the oven should be at its best—but instead, it shuts down. Understandably, our customer was frustrated. They had a beautiful kitchen and relied on this appliance to cook for their family—but now they were stuck guessing what the code meant.

To make matters worse, their digital display was so dim they could barely read the settings.

They didn’t know if it was one problem or two—or if it would mean replacing the entire unit.

The Diagnosis: Relay Board & Control Board Issues

When our technician arrived, we diagnosed two separate but common issues with this model:

F50 Error – Relay Board Failure

The F50 code typically points to a relay board issue. This board controls many of the oven’s core functions—so if it fails, the oven won’t complete its heating cycle.

Dim Display – Control Board Weakening

The faint or fading display was caused by a control board issue—a separate but related problem. As these boards age, the LED screens often lose brightness.

We replaced both boards—and just like that, the oven was fully functional and readable again.

What Most People Don’t Know About Appliance Boards

Here’s the behind-the-scenes part most customers never hear:

1. Boards Come With a CORE (Like a Car Battery)

When we order certain control or relay boards, they include a core charge—usually around $60. This is a refundable deposit if we return the old board to the distributor.

So yes, we’ll be asking for that part back, not because we want a souvenir—but because it saves everyone money.

2. These Parts Can’t Be Preordered “Just in Case”

Distributors will not accept returns on boards once shipped. That means we can’t just order one ahead of time unless the issue is clearly diagnosed. It protects you from paying for a part you may not need—and protects us from passing along restocking fees.
